My Comments

An increasing trend we are seeing with regular desktop and laptop computers is that they are being used for voice and video telephony. Thu is being driven by messaging apps of the Skype, Facebook Messenger, WhatsApp and Viber kind being ported to desktop operating systems; along with softphone applications that provide telephony functionality being made available for these operating systems. The softphone applications, along with Skype are even legitimising this usage case with laptops in the business environment turning them in to secondary or replacement phone extensions.

Headsets like the JBL E45BT Bluetooth headset are used with laptops to make voice calls with messaging apps and soon this will happen for mobile telephony

With these setups, you can talk with the caller using the computer’s integrated or attached microphone and speakers. Or, should you want the same level of privacy associated with holding a handset up to your ear, you can talk to the caller using a wired or Bluetooth headset, of which I have reviewed many on HomeNetworking01.info.

Microsoft and others in the “open-frame” computing world are pushing along with the Always Connected PC which runs ARM RISC microarchitecture rather than the traditional Intel-based CISC kind. These ultraportable computers will also be equipped with a wireless broadband modem that is authenticated using eSIM technology.

The idea is to eventually have these computers become like a smartphone with them linked to the cellular mobile network. It is also alongside the fact that today’s smartphones are effectively pocket computers running a mobile operating system.

It could be easy to say that the Always Connected PC concept is irrelevant because one can “tether” a computer to a smartphone to have access to the mobile broadband service, whether through a USB connection or a Wi-Fi-based “hotspot” function that mobile operating systems support. Or we can simply connect our computers and phones to Wi-Fi networks including publicly-accessible networks like hotspots. For that matter, computers can also be connected to other network types like Ethernet or HomePlug AV networks.

Smartphones now are pocket computers

Let’s not forget that the GSM Association and the Wi-Fi Alliance are looking at Wi-Fi networks as a way of providing data-offload functionality. This is through mobile carriers like BT and Telstra offering FON-style community Wi-Fi networks and the Wi-Fi Alliance using Passpoint / Hotspot 2.0 as a way to provide hands-off login to public-access networks.

The Wi-Fi functionality is also being taken further in the context of smartphone-based voice telephony with the use of VoWLAN as another call-transport option for these devices. Some mobile telcos like Telstra even use this as a way to provide voice telephony continuity to their customers if they can’t reach the cellular network but can use Wi-Fi-based Internet.

The focus now is towards the concept of always-connected portable computing with a secure and consistent connectivity experience. This is being brought on through the use of 5G mobile-broadband technology and the interest in edge computing which provides support for localised data processing and storage in a cloud environment.

The eSIM is being pitched as a way to provision mobile service in an online manner, especially to vary the service to suit one’s needs or switch to a competing mobile telco. It also is placing pressure upon mobile telcos to adopt a “service-focused” approach with the idea of having multiple devices on the same mobile account and plan, ringing to the same mobile number and using the same data allowance. The goal with mobile telephony will then be to make or take a voice or video call or send and receive messages on the device that you currently are using rather than changing to a different device for that task.

Connected cars even to be another logical device for one’s mobile service account.

This concept has been driven by the Apple Watch and will be pushed on with smartwatches that have built-in mobile broadband modems. But it will be extended through other devices like smartphones, Always Connected PCs and connected vehicles. There is also the idea of implement the equivalent of a local area network across devices tied to the same service and this will be driven by the trend towards ubiquitous ambient computing.

A question that will come about is the ability to maintain multiple different services on the same physical device whether from the same telco or different telcos. This will be about maintaining separate services for business and private use. Or it could be about travellers who want to maintain a local service while at their destination along with their “home” service. This is a feature that is of relevance in countries where cross-border commuting is the norm thanks to land borders or short affordable ferry rides.

This could be addressed through support for multiple services including the ability to provision a cluster of multiple devices with the one service simultaneously. This same issue can also address the ability for us to use the conventional Internet service based around a hardwired broadband service with a Wi-Fi and / or Ethernet local network in the premises.

What I see out of this new trend is that if your computing device has mobile broadband or connection to the Internet via a local-area network, along with a speaker and microphone, it will become the one-stop computing and communications device. It doesn’t matter what shape or size it is in, being a smartphone, laptop or whatever. As well, the right-sized computing device will serve your computing and communications needs as you see fit.

Product Review–Dell XPS 13 8th Generation Ultrabook (9360)

Introduction

I have been following the Dell XPS 13 series of clamshell Ultrabooks which are an effort Dell have been undertaking to get the right mix of performance, build quality and functionality in an affordable package. It was also about not losing sight of this goal while evolving the model towards newer technologies and specifications. Now I have the chance to review the latest iteration of this series known as the “9360” series and equipped with the 8th Generation silicon in the higher-specified packages.

This computer represents the latest in the Dell XPS 13 clamshell Ultrabook dynasty and has a technical refresh with the new Intel 8th Generation silicon. There is the “9370” series which is more expensive and implements more of the USB-C connectivity in lieu of the USB-A connections and exclusively uses Intel 8th Generation silicon.

Dell has been maintaining the key features that make the XPS 13 series earn its keep as a value-for-money all-round Ultrabook rather than adding too many “bells and whistles”. As I referred to in a previous article on the XPS 13, I was describing this effort as “ticking all the boxes” for what the market expected.

Aesthetics and Build Quality

Dell XPS 13 9360 8th Generation clamshell Ultrabook

Dell XPS 13 9360 8th Generation clamshell Ultrabook

The Dell XPS 13 didn’t come across as being flimsy or weak in any way. Rather it maintained the similar build quality and aesthetics of a good-quality clamshell Ultrabook.

There was a situation that I noticed where the computer was slightly warmer underneath during a software update but it wasn’t uncomfortable to use when you are using it on your lap. Luckily the heat buildup occured in the centre of the laptop’s base but was dispersed thanks to the metal housing. It will be a situation to expect with most of the ultraportable computers due to their small size.

User Interface

The backlit keyboard is accurate for touch-typing and the backlighting is not too dominant when used in daylight or average room light. The backlighting also does properly turn off when you aren’t using the keyboard.

The precision multi-touch trackpad works properly with all of the advanced multi-finger gestures as well as single-finger mousing around. It doesn’t act too hair-trigger and select things it shouldn’t when you are typing even if you use the XPS 13 Ultrabook on your lap.

The integrated fingerprint reader works tightly with Windows Hello and is accurate most of the time. Having very dry fingers after, perhaps, outdoor work may cause it not to be accurate and you may have to log in with your Windows PIN. As well, during the initial setup phase, make sure that the fingerprint reader catches your fingerprint at different angles.

The Intel integrated video chipset works smoothly with streamed content after I had viewed an overseas video through this laptop. But personally, I would see this chipset serve most ordinary computing tasks effectively. I am also pleased about Dell having the XPS 13 Ultrabook equipped with the necessary Thunderbolt 3 port for those of us who want to have that bit of extra video performance provided by an external graphics module.

The Waves MaxxAudio still is about trying to improve the integrated speakers’ sound. But it is still the same issue with ultraportable notebook computers that you have to use headphones, external speakers or a sound system to achieve better sound from these computers.

Connectivity, Storage And Expansion

The 256Gb solid-state drive is the only integrated secondary-storage option available across the Dell XPS 13 series. This would offer the right amount of storage for most needs but you may have to use a USB hard disk if you are wanting to offload photos and the like to keep essential data on the SSD.

Speaking of which, there is an integrated standard SD-card reader which is useful for those of us who use digital cameras for our photography. As I have experienced, you don’t need to deal with USB-based SD card readers if you deal with photos from your camera.

If you are dealing with newer networking equipment, the Wi-Fi networking infrastructure performs very adequately and maintains the expected throughput. The Bluetooth functionality works very well even for streaming audio to a headset.

Dell has maintained the Thunderbolt 3 / USB-C port on the XPS 13 Ultrabook to assure users of a path towards higher-performance graphics. This could allow a user to purchase an external graphics module for better graphics performance “at home” or “at work”, while it provides USB Power Delivery connectivity as an alternative power input if you use an expansion module with power-supply abilities to that standard.

Battery Life

The reviewed configuration of the Dell XPS 13 Ultrabook is within the expectations for a portable computer to have a long battery live and I was able to do regular computing and Internet tasks for most of the day without finding that it is going to die out quickly.

I was able to stream a video for 90 minutes with the sound coming via a Bluetooth headset and found that the Dell XPS 13 Ultrabook had 87% battery capacity at the end of the video. This was assuring proper glitch-free throughput and smooth playback.

One of the factors that I see with achieving the ideal battery life is the review configuration being kitted out with an integrated screen that sticks with the ideal 1920×1080 screen resolution which I would find as being fine for most users.

Other Usage Notes

Dell XPS 13 9360 8th Generation rear viewI have used the Dell XPS 13 Ultrabook in front of other people and they have seen it as a highly portable highly viable computer to use “on the road”. Infact I was showing it in front of a man who was considering what to purchase for a “travel” laptop and he saw this as a good example of what he wanted to use. This is for soneone who maintains a desktop computer with the large screen as their main home computer.

Limitations And Points Of Improvement

Dell would need to avoiding losing the vision of what the XPS 13 Ultrabook is about – a robust capable ultraportable computer that offers what most users want for the right price. It is similar to what Toyota have been doing with their Hiace vans and Hilux pickup trucks – improving on these vehicles without losing sight of the reputation they have earnt over the generations.

A question that will come across to Dell is whether to maintain a large range of XPS 13 configurations for all markets or not. This may be an approach to provide some affordable variants that can appeal to students and the like while offering higher-performance configurations for those who can afford them.

Dell would have to maintain at least one Thunderbolt 3 connection on all computers of the series in order to allow users to “pep up” the graphics with an external graphics module. In the same context, they could easily offer one or more of these external graphics modules as an optional accessory for these systems.

As Dell evolves the XPS 13 series, they could easily consider supplying a 512Gb SSD as an integrated storage option for some of the configurations. This would be at the time that this capacity becomes affordable to specify for the same physical size. It could then make the XPS 13 Ultrabooks earn their keep as a sole computing device. Similarly, they could offer a touchscreen with a 1920×1080 resolution as an intermediary display option so you are still able to stay with that resolution to conserve battery runtime yet benefit from touch-driven operation.

Conclusion

Dell is keeping the performance, functionality and quality to the same expectations for this generation of the XPS 13 Ultrabook as they have done for the previous generations of this Ultrabook dynasty.

Personally I would see the 9360 Series of the XPS 13 as a machine for those of us who want more value for our money. In some cases, I would recommend even looking at variants with the prior-generation Intel processor for those of us who are on a budget yet want some performance out of these machines.

Ford Mustang fastback at car show

Dell used the same approach as Ford did in the 1960s with the original Mustang

During the heyday of the “good cars” that was represented through the 1960s and 1970s, the major vehicle builders worked on various ways to approach younger drivers who were after something that was special.

One of these was to offer a “pony car” which was a specifically-designed sporty-styled two-door car that had a wide range of power, trim and other options yet had a base model that was affordable to this class of buyer. Another was to place in to the product lineup for a standard family-car model a two-door coupe and / or a “sports sedan” / “sports saloon” that is a derivative of that standard family car and built on that same chassis but known under an exciting name with examples being the Holden Monaro or the Plymouth Duster. This would be available as something that young people could want to have when they are after something impressive.

Both these approaches were made feasible through the use of commonly-produced parts rather than special parts for most of the variants or option classes. As well, there was the option for vehicle builders to run with variants that are a bit more special such as racing-homologation specials as well as providing “up-sell” options for customers to vary their cars with.

The various laptop computer manufacturers are trying to work on a product class that can emulate what was achieved with these cars. Here, it is to achieve a range of affordable high-performance computers that can appeal to young buyers who want to play the latest “enthusiast-grade” games on.

Dell Inspiron 15 Gaming laptop

The Dell Inspiron 15 7000 Gaming laptop – to be superseded by the Dell G Series

One of the steps that has taken place was to offer a high-performance “gaming-grade” variant of a standard laptop model like the Dell Inspiron 15 Gaming laptop, one of which I had reviewed. This approach is similar to offering the “Sport” or “GT” variant of a common family-car model, where the vehicle is equipped with a performance-tuned powertrain like the Ford Falcon GT cars.

But Dell have come very closer to the mark associated with either the “pony cars” or the sporty-styled vehicles derived from the standard family-car model with the release of the Inspiron G series of affordable gamer-grade laptops. Here, they released the G3, G5 and G7 models with baseline models being equipped with traditional hard disks and small RAM amounts. But these were built on a very similar construction to the affordable mainstream laptops.

These models are intended to replace the Inspiron 15 Gaming series of performance laptops and it shows that they want to cater to the young gamers who may not afford the high-end gaming-focused models. As well, the G Series name tag is intended to replace the Inspiron nametag due to its association with Dell’s mainstream consumer laptop products which takes the “thunder” out of owning a special product. This is similar to the situation I called out earlier with sporty vehicles that are derivatives of family-car models having their own nameplate.

The G3, which is considered the entry-level model, comes with a 15” or a 17” Full-HD screen and is available in a black or blue finish with the 15” model also available in white. It also has a standard USB-C connection with Thunderbolt 3 as an extra-cost “upsell” option along with Bluetooth 5 connectivity. This computer is the thinnest of the series but doesn’t have as much ventilation as the others.

The G5 which is the step-up model, is a thicker unit with rear-facing ventilation and is finished in black or red. This, like the G7 is equipped with Thunderbolt 3 for an external graphics module along with Bluetooth 4 and has the ability for one to buy a fingerprint scanner as an option. Also it comes only with a 15” screen available in 4K or Full HD resolution.

The G7 is the top-shelf model totally optimised for performance. This is a thicker unit with increased ventilation and implements high-clocked CPU and RAM that is tuned for performance. It has similar connectivity to the G5 along with similar display technology and is the only computer in the lineup to implement the highly-powerful Intel Core i9 CPU that was launched as the high-performance laptop CPU as part of the latest Coffee Lake lineup.

All the computers will be implementing the latest Coffee Lake lineup of Intel high-performance Core CPUs, being the Core i5-8300HQ or Core i7-8750H processors depending on the specification. In the case of the high-performance G7, the Intel Core i9-8950HQ CPU will be offered as an option for high performance.

They all use standalone NVIDIA graphics processors to paint the picture on the display with a choice between the GeForce GTX1060 with Max-Q, the GeForce GTX1050Ti or the GeForce GTX1050. What is interesting about the GeForce GTX1060 with Max-Q is that it is designed to run with reduced power consumption and thermal output, thus allowing it to run cool in slim notebooks and do away with fans. But the limitation here is that the computer doesn’t have the same kind of graphics performance compared to a fully-fledged GeForce GTX1060 setup which would be deployed in the larger gaming laptops.

Lower-tier packages will run with mechanical hard drives while the better packages will offer use of hybrid hard disks (increased solid-state cache), solid-state drives or dual-drive setups with the system drive (C drive with operating system) being a solid-state device and data being held on a 1Tb hard disk known as the D drive.

I would see these machines serving as a high-performance solo computer for people like college / university students who want to work with high-end games or put their foot in to advanced graphics work. As well, I wouldn’t put it past Lenovo, HP and others to run with budget-priced high-performance gaming laptops in order to compete with Dell in courting this market segment.

Should I buy a laptop with integral mobile-broadband modem?

Article

Snapdragon smartphone electronics in 2-in-1 laptop press picture courtesy of Qualcomn

Is it worth it to consider integrated mobile-broadband modems in your next laptop purchase

Why you might (and might not) want a PC with LTE | Windows Central

My Comments

A trend that will be affecting portable computers will be the rise of laptops and notebooks that are equipped with an integrated mobile-broadband modem.

Previously this was a feature associated with premium business-grade laptops as an extra-cost option, but this is being encouraged as a product differentiator for a larger range of portable computers targeted at consumers and small businesses. The key feature callout will be that the computer is equipped with LTE connectivity and this feature has been brought along thanks to Windows 10 and the “Always Connected PC” vision.

Initially such computers will authenticate to the mobile network with a standard SIM card installed in a reader somewhere on the computer’s chassis. But newer designs will move towards an eSIM module integrated in the computer which provides for “over-the-air” provisioning by the telco or their agent.

Why this trend?

"Mi-Fi" portable wireless router

No need to use a Mi-Fi to obtain Internet on the road with your laptop if you have an integrated mobile-broadband modem but some situations may be better served with these devices

There is the feasibility of a secure connection anywhere within reach of mobile networks. It is something you may not benefit from when using a lot of legacy-configured public-access Wi-Fi networks.

As well, you avoid the need to set up Wi-Fi or USB tethering on your smartphone or tablet, or to use a “Mi-Fi” mobile-broadband router. Similarly, you shouldn’t need to worry about draining your battery in your “Mi-Fi” router or smartphone to keep the connection alive.

You also benefit from a faster link between the modem and the computer which is important for setups implementing LTE, because a lot of USB mobile-broadband modems don’t implement the newer variants of the USB standard. There is also the fact that an integral mobile-broadband modem design allows for a larger mobile-broadband antenna to be integrated in the laptop computer, rather than having to design a small mobile-broadband antenna to keep a relatively-compact product design for that “Mi-Fi”, USB modem stick or smartphone.

The laptop’s battery shouldn’t be affected in this case thanks to Windows 10 implementing “data-saver” and battery-management logic. There is also the fact that Windows 10 will implement a class driver and authentication software within the operating system’s code so you don’t need to run any extra software to get on board with mobile broadband.

There are some disadvantages with this approach

One of these is that the host computer may be fixed with the “current” technology and may not be able to take advantages of newer technologies or wavebands that the telco you subscribe to offers.

This can be an issue with the pending 5G mobile-broadband standards or Australian telcos like Telstra exploiting lower wavebands in the mobile spectrum with the goal to assure greater coverage in Australia’s larger rural areas but yield high data throughput. But if the mobile-broadband modem operates on a “software-defined” approach where it can work with extra subsequently-available firmware that can adapt to these situations, it may not be an issue.

They may not work optimumly in one of these metal-clad caravans

Another factor is the integrated-modem approach may not work properly in some usage scenarios where you have a strong signal in certain areas but a weak signal in other areas. This can be of concern for those of us who want to use our computing equipment in a post-1950s caravan or a campervan / motorhome with the vehicle’s housing being predominantly metal which can reduce radio throughput.

In these situations, you may have to use a USB modem on a long USB cable run or use a “Mi-Fi” router with some situations calling for the “two-piece” approach put forward by Solwise.

Another situation you may need to think of is whether you are intending to use multiple mobile devices on the road with the one mobile-hroadband service. Here, you may find that a “Mi-Fi” router set up as the hub of a mobile local-area network may be a better answer to your needs. This is more so if you are running many devices like mobile NAS units, Wi-Fi-capable mobile printers or Wi-Fi-capable digital cameras along with tablets that may not be equipped with mobile broadband.

Of course you will need to use a pre-paid or post-paid mobile broadband service that is provisioned in a manner compatible with your computer. In these cases, such services would be offered as a “SIM-only” or “existing-device” package where you aren’t buying a device under any form of subsidy.

Telcos can easily answer this through the provision of starter prepaid plans offered as part of the package when you buy your computer or by allowing the Windows Store that is part of Windows 10 to work as their agent. Of course you can front up to their bricks-and-mortar outlet to buy a “SIM-only” or “existing-device” prepaid plan for your computer.

On the other hand, most of the telcos will allow you to annex your new integrated modem to your post-paid mobile plan. This will be an important approach for those telcos who are offering a “shared-data” or “family” plan or underscore value for money with these plans.

What to look for

SIM card

Make sure that the SIM card fits your mobile-broadband-equipped laptop or that your service provider supports an eSIM for suitably-equipped laptops

You may have to be sure that your mobile-broadband-equipped laptop is able to connect with the mobile-broadband service that you want to use. Firstly you will have to pay attention to whatever SIM type your computer uses for authentication to the service that you choose.  That will be the kind of information you will have to supply to your mobile-broadband carrier when you are buying mobile-broadband service, or wish to buy other mobile-broadband devices which are “SIM-compatible” with your laptop with a view to moving our service amongst these devices.

As well, you would need to make sure your laptop does work “across the board” with all of the mobile-broadband services that you intend to yous. For example, if you wish to use a service like Telstra that prides itself on extensive coverage in rural areas, you may need to be sure that the mobile broadband modem can cover the lower ends of the spectrum used by this carrier. Another example would be to use it in a range of countries which work on different mobile-broadband frequencies.

People who run a post-paid mobile account should look towards being able to annex the data service used by the laptop’s integrated modem with their account. This can assure them of “many eggs in one basket” with the advantages such as paying through one bill and benefiting from deals that exploit this fact. As well, some providers may operate a deal with multiple SIMs for one number and underscore this for eSIM setups.

Conclusion

Here, it depends on your needs whether paying the extra expense for a laptop configuration with an integral mobile-broadband modem is worth it for you.

Microsoft to improve user experience and battery runtime for mobile gaming

RAVEN: Reducing Power Consumption of Mobile Games without Compromising User Experience (Blog Post)

My Comments

A common frustration that we all face when we play video games on a laptop, tablet or smartphone is that these devices run out of battery power after a relatively short amount of playing time. It doesn’t matter whether we use a mobile-optimised graphics infrastructure like what the iPad or our smartphones are equipped with, or a desktop-grade graphics infrastructure like the discrete or integrated graphics chipsets that laptops are kitted out with.

What typically happens in gameplay is that the graphics infrastructure paints multiple frames to create the illusion of movement. But most games tend to show static images for a long time, usually while we are planning the next move in the game. In a lot of cases, some of these situations may use a relatively small area where animation takes place be it to show a move taking place or to show a “barberpole” animation which is a looping animation that exists for effect when no activity takes place.

Microsoft is working on an approach for “painting” the interaction screens in a game so as to avoid the CPU and graphics infrastructure devoting too much effort towards this task. This is a goal to allow a game to be played without consuming too much power and takes advantage of human visual perception for scaling frames needed to make an animation. There is also the concept of predictability for interpreting subsequent animations.

But a lot of the theory behind the research is very similar to how most video-compression codecs and techniques work. Here, these codecs use a “base” frame that acts as a reference and data that describes the animation that takes place relative to that base frame. Then during playback or reception, the software reconstructs the subsequent frames to make the animations that we see.

The research is mainly about an energy-efficient approach to measuring these perceptual differences during interactive gameplay based on the luminance component of a video image. Here, the luminance component of a video image would be equivalent to what you would have seen on a black-and-white TV. This therefore can be assessed without needing to place heavy power demands on the computer’s processing infrastructure.

The knowledge can then be used for designing graphics-handling software for games that are to be played on battery-powered devices, or to allow a “dual-power” approach for Windows, MacOS and Linux games. This is where a game can show a detailed animation with high performance on a laptop connected to AC power but allow it not to show that detailed animation while the computer is on battery power.

Press Release highlighting what was shown at CES 2018

My Comments

Dell used the Consumer Electronics Show 2018 to premiere a 15” ultraportable 2-in-1 convertible laptop that underscores what Intel’s new G-series CPU / GPU combination chips are about.

Intel Corporation is introducing the 8th Gen Intel Core processor with Radeon RX Vega M Graphics in January 2018. It is packed with features and performance crafted for gamers, content creators and fans of virtual and mixed reality. (Credit: Walden Kirsch/Intel Corporation)

This is what drives the Dell XPS 15 2-in-1

This laptop, which is the smallest thinnest 15” portable, comes in with a thickness of 16mm when either closed or folded over as a tablet. This is brought about due to the implementation of the single-die chip which has the Intel 8th Generation Core CPU and an AMD Radeon RX Vega M GL graphics processor with 4Gb of display memory to “paint” with. The computer press see this setup being equivalent to an NVIDIA GeForce GTX 1050 dedicated GPU.

It is allowing Dell to pitch the XPS 15 2-in-1 as an “enthusiast-grade” lightweight 2-in-1 laptop with the kind of performance that would please people who are into multimedia and animation work or want to play most of the newer games.

Another influence is the use of a “maglev” keyboard which uses magnets to provide the tactile equivalent of a keyboard with a deeper throw. But this allows also for a slim computer design.

The new Dell XPS 15 2-in-1 computer can be configured with an Intel Core i5 as the baseline option or an Intel Core i7 as the performance option. The touchscreen can be a Full HD display as a baseline option or a 4K UltraHD display with the 100% Adobe colour gamut for the premium option.

The RAM available ex-factory can range between 8Gb to 16Gb while the storage capacity that is available ex-factory ranges from 128Gb to 1Tb on a solid-state drive. Personally, I would like to see the minimum storage capacity available being 256Gb. The only removable storage option integrated in this computer is a microSD card slot, which may require you to use a microSD card and SD card adaptor in your camera or carry a USB-C SD card reader for your digital camera’s SD memory card.

The connectivity options for this computer come in the form of 2 Thunderbolt 3 and 2 standard USB-C sockets. These all support USB Power Delivery which means that they serve as a power input from the laptop’s charger, along with PowerShare “sleep and charge” and DisplayPort alt mode. The fact that this laptop has Thunderbolt 3 connectivity means that it could be connected to better-performing graphics processors installed in external graphics modules and can even lead towards “workstation-grade” graphics once teamed with a “card-cage” graphics module that is kitted out with an NVIDIA Quadro workstation graphics card.

The baseline price for this model intended to be available in the USA in April is expected to be US$1299. Personally I would see the Intel CPU/GPU chipset preparing the path for a slow return of the “multimedia laptop” but in a lightweight manner and with a larger battery.

My Comments

Intel have used the Consumer Electronics Show 2018 to premiere a system-on-chip that is to affect how portable and small-form-factor computers will perform.

This chip, part of the 8th generation of Intel CPUs contains an 8th Generation Core i5 or i7 CPU along with an AMD Radeon RX Vega M discrete graphics processor and an Intel HD 630 integrated graphics processor.

It is positioned in the Intel 8th Generation processor lineup which is like this:

  • U-Series processors that are only equipped with an Intel UHD integrated graphics processor. One of these is installed in the latest iteration of the Dell Inspiron 13 7000 which I reviewed for this site. Here this family of processors is pitched towards what most people will want for their personal and business computing needs.
  • G-Series processors that are also equipped with the above-mentioned Radeon RX Vega M graphics processors. These are pitched as a performance option which would appeal to most gamers, virtual-reality / augmented-reality enthusiasts and content creators who want a machine with that bit of “pep” when it comes to graphics.
  • H-Series processors which are pitched towards those who want the highest performance and would rely on a dedicated graphics processor. Here, they would apply to the gaming rigs and workstations where the goal is for full-on performance.

What is special about these Intel processors

These Intel processors place the Core CPU and the AMD GPU on the same die along with a stack of dedicated graphics RAM and they are linked using the EMIB (Embedded Multi-Die Interconnect Bridge). This arrangement provides a short link between each component to provide for quick data transfer. There is also a power-optimised design to allow for efficient power use by all the components on the chip.

There are two variants of the graphics subsystem available for the chipset known as the GL and the GH. The GL (Graphics Low) variant is optimised with less than 65 watts power draw and is pitched towards “thin-and-light” laptops and the like. The GH (Graphics High) variant is a higher-performance variant that draws less than 100 watts of power and only comes with the Core i7 CPU. Here, it is pitched towards the small-form-factor desktops, all-in-ones and similar computers that normally work from a constant power supply.

All that horsepower in those dies can allow the computer to paint an image across nine display devices at once. The fact that there is an integrated graphics processor on board can allow these “system-on-chip” setups to engage in “performance / economy” switching to maximise power efficiency.

Where are they being premiered in?

The first two variants are the Core i7-8809G CPU with Radeon RX Vega M GH for performance and the Core i7-8705G CPU with Radeon RX Vega M GL as the value option.

These are being released to go with the the Hades Canyon series of “Next Unit Of Computing” small-form-factor computers. Both of these computers are available as a kit which can support 32Gb (2 x 16Gb) DDR4 RAM and 2 M2-compliant solid-state drives. These have plenty of USB connections including 2 Thunderbolt-3 sockets and can connect to your home network via one of two Gigabit Ethernet sockets or 802.11ac Wi-Fi.

What kind of impact do I see these Intel chips have on computer design?

One class of computer that will definitely benefit will be the portable computers that most of us will consider purchasing. The computing press see a benefit when it comes to “enthusiast-class” laptops where they will benefit from a slimmer chassis along with the ability to run in a quiet and cool manner yet deliver the performance they are known for. It will also lead to longer battery runtimes like nine hours even while engaging in high-performance work.

But I see computer manufacturers deploying these CPU/GPU chipsets as the standard expectation for the mainstream 13”-15” home or business laptops that are their “bread and butter” products. Typically these machines have a larger chassis than the ultraportables and are valued by most users for factors like durability, connectivity and ability to choose different configuration options. Here, the manufacturers can design in larger battery packs or extra peripherals like multiple storage devices or optical drives or even improve how these computers sound by using larger speakers.

Let’s not forget that the computer manufacturers could also offer in their ultraportable lineup a run of computer products that are thin and light yet powerful.

As far as sessile computers are concerned, I would see that ultra-small “next unit of computing” units benefit along with the all-in-ones that have the computing electronics part of the screen. Other traditional desktop computers that could also benefit include those that are the same size and shape as typical consumer-electronics devices.

Conclusion

I would see Intel’s 8th-generation “Coffee Lake” G-series CPU/GPU hybrid chip being something that offers greater potential for how the personal computer is designed without losing the desire for more computing power.

My Comments

Microsoft had made some attempts at bringing Windows to the ARM RISC microarchitecture with a view to bringing forth cheaper computers. But they had failed thanks to silicon based on traditional Intel x86/x64 microarchitecture being offered at very cheap price points and able to natively run a large roster of software already available for that platform.

But they, along with Qualcomn who supply the silicon for most of today’s smartphones, have re-approached this through the vision of an ultraportable laptop computer or tablet that implements the same technology as one of the recent high-end smartphones and phablets. This has been drawn out alongside the recent crop of highly-capable 11”-14” 2-in-1 laptops that are making a strong appeal as a highly-capable alternative to the iPad and Android-based tablets.

But the computers that represent the “Always Connected PC” product class integrate a large battery along with the LTE-based wireless-broadband modem, both of which allow for a long time of computer activity without the need of Wi-Fi or daily charging. These would also support eSIM which allows for over-the-wire provisioning of mobile broadband service, including the ability to provide “international-focused” service for people roaming around the world. HP and ASUS have premiered a detachable 2-in-1 and a convertible 2-in-1 which are based on this technology.

Microsoft is pushing the Always-Connected PC for the workplace with a focus towards a managed computing environment. Here, it is about avoiding the need to connect to insecure public-access Wi-Fi networks or worry about whether you have the laptop’s power supply with you when you head to work or make that business trip.

I see it more as an answer to Apple’s iOS platform, Google’s ChromeOS platform and Samsung’s interpretation of the Android platform where the goal is to cater to a mainstream productivity-focused computing environment for work or school.

Here, the focus would be about interacting with cloud-based business / education software whether as a Web app or as platform-native software or simply working with information using standard office-productivity software, perhaps with some video playback or mobile-grade gaming. I also see this as a way for Microsoft to aggressively compete against the iPad in the household, education and business environment by encouraging its partners to offer tablets and 2-in-1s that have the same operational qualities as that tablet.

But it wouldn’t displace the Intel / AMD x86/x64-based computers which would be focused towards applications where performance is of importance such as serious gaming or photo / video editing. But as for running Windows software, the ARM-based variants of Windows will be implementing an x86 emulation layer that allows 32-bit Windows software to run on these computers. This is while Windows software developers who package software for the Windows Store will be encouraged to deploy code native to x86, x64 and ARM microarchitectures.

The big challenge now is for software developers and games studios to port the software that is on the iOS or Android platforms towards the Windows 10 platforms on all the microarchitectures. It would them make it viable for Windows to continue as a third force for “non-handheld” mobile computing.

Product Review–Dell Inspiron 13 7000 2-in-1 laptop (Intel 8th Generation CPU)

Introduction

I am reviewing the latest version of the Dell Inspiron 13 7000 8th Generation which replaces the Inspiron 13 7000 7th Generation models that I previously reviewed. Here, this is based around implementing the Intel Kaby Lake Refresh technology which is a step towards making mainstream portable computers capable of doing most computing tasks without being seen as underpowered cousins of desktop computers.

There is also the Dell Inspiron 13 5000 2-in-1 series which omits the USB Type-C connection and the Intel RealSense camera but available at a cheaper price. These are available in three different configurations, one with an Intel Core i5 CPU, 8Gb RAM and 256Gb SSD; a step-up variant with a Core i7 CPU and the top-shelf model with 16Gb RAM and 512Gb SSD storage.

Aesthetics and Build Quality

Now with 8th Generation Intel silicon

Thee Dell Inspiron 13 7000 8th Generation convertible laptop has the same aesthetics and build quality as the previous two generations. This means that it has the same metal finish and housing but also comes across as being very durable. As well, Dell have embraced the narrow display bezel trend started with the XPS 13 Series and implemented it in to this lineup, making for an effectively larger display space in a relatively compact machine.

There is still a smooth action involved when converting it between a laptop and tablet mode which makes for something that can be easily used by most people.

… as a presentation viewer

Like with the prior generation of the Dell Inspiron 13 7000, the cooling vent is located near the hinges yet there is a bit more heat build-up that can occur with basic gaming. It doesn’t exhibit this kind of heat buildup during basic computing tasks. This is even though I am dealing with the newer Intel Core i7 silicon which is known to be more powerful than prior versions.

User Interface

The Dell Inspiron 13 7000 uses an illuminated keyboard that lights up as needed. But it is wide enough to type with accurately and has a shallow key throw but that is enough for proper tactile feedback.

… as a tent mode

Like with most laptops, the function keys default to the volume, multimedia and display controls. But with this one, press the Fn key and ESC key to toggle on the normal function-key behaviour.

The trackpad and touchscreen work properly and effectively. In the case of the trackpad, I have not noticed any situation where the pointer moved around while I was typing, thus being less of a distraction.

Audio / Video

The Waves MaxxAudio sound-tuning software does improve the sound but the internal speakers have that tinny sound common with laptops. But I would find best results when you use the Dell Inspiron 13 7000 with with headphones, external speakers or sound system. Most likely, you will end up needing to use headphones to avoid distracting others when you use this computer in a public place for multimedia, videocall, gaming or similar activities.

The Intel UHD 620 integrated graphics provides the kind of performance you would expect for most computing tasks including the occasional gaming and similar tasks that most of us would do. Here, you would see smooth video playhack for most of these tasks.

Like with all consumer-grade computers, there is still the glossy display which can become dirty very quickly and show reflections easily.

Connectivity, Storage And Expansion

Like with the prior iterations of the Dell Inspiron 13 7000 2-in-1, the connectivity options are essentially the same with the 2 USB 3.0 ports and the 1 USB Type-C port as well as the HDMI video port.

Personally I would like to see Dell implement the Thunderbolt 3 port in the Inspiron 13 7000 Series computers but this will have to wait for a full model-level revision rather than a silicon-level refresh.

Right hand side- USB 3.0 port, SD card reader

The whole of the Inspiron 13 7000 range offers the kind of capacity on the solid-state drives that would be expected for most people to benefit from with these drives living up to the promise of quick access. This also includes the fact that even the haseline variants have that healthy 256Gb capacity that would suit most users even as a main or sole computer.

Battery Life

The use of Intel 8th Generation silicon for the CPU and graphics hasn’t made a difference to the Dell Inspiron 13 7000’s battery life although you are really allowing the computer to perform better using the newer technology.

Other Usage Notes

One of the men who run the Melbourne Men’s Shed was impressed with the Dell Inspiron 13 7000’s specifications even though the review sample is the top-shelf model. He was also impressed by the convertible design that this unit has.

Similarly some hotel staff wore impressed by the convertible design and described it as looking similar to a recent iPad when they saw it at first glance.

Limitations And Points Of Improvement

Dell could “carve out” the Inspiron 13 2-in-1 product range for those of us who aren’t necessary after a very light ultraportable 2-in-1 but want something that is portable enough for most applications.

Here, they could implement the 8th-generation Intel Core processors across the range as well as providing some of the premium models in the lineup with Thunderbolt 3 connectivity. This is more so for those of us who want to run them with external graphics modules.

Similarly, Dell could offer one or two configurations with Intel Iris higher-performance integrated graphics as a product differentiator. This would appeal to those of us who want that bit more out of the graphics abilities.

As for enablement of options like PowerShare “sleep and charge” or anything that is only available in the computer’s BIOS, Dell could provide an app that allows some of these options to be manipulated from the Windows interface rather than having to reboot your computer to achieve that goal.

Conclusion

I would recommend this variant of the Dell Inspiron 13 7000 Series 2-in-1 comvertible computer for those of us who want value for money and want something that is powerful for most computing tasks. Even the improvement that Dell offers by implementing the Intel Kaby Lake R silicon still underscores the value for money that they are known for with the products.

AMD now launches the Ryzen processor for portable computing

AMD

Ryzen Processors (Product Page)

My Comments

Just lately, Intel released their 8th generation Kaby Lake R family of “Core i” processors which are targeted at portable computers. These powerful CPUs that were optimised for portable use were issued with an intent to compete against AMD’s upcoming release of their Ryzen processors, pitched at a similar usage scenario. Various press articles even drew attention towards being able to play more powerful PC games on these lightweight computers rather than limiting their scope of activity.

Now AMD have released this silicon which also integrates the Radeon Vega graphics-processing silicon for the laptop market. This is where they are targeting the Ryzen 7 2700U CPU and the Ryzen 5 2500U 15-watt processors and instigating a race against Intel’s Kaby Lake R horsepower and QHD integrated graphics.

What I see of this is that Intel and AMD will make sure that this generation of ultraportable computers will be seen to be more powerful than the prior generations. Think of using an Intel Kaby Lake R Core i7 or AMD Ryzen 7 powered 2-in-1 for most photo-editing tasks or as a “virtual turntable” in the DJ booth, activities that wouldn’t be associated with this class of computer.

At the moment, Intel hasn’t licensed the Thunderbolt 3 connectivity standard across the board including to AMD, which will see it as a limitation when it comes to allow users to upgrade graphics capabilities on their AMD Rysen-equipped laptops using an external graphics module.

One way Intel could approach this is to divest the Thunderbolt standards and intellectual property to an independent working group like the USB.org group so that manufacturers who implement Intel, AMD, the ARM RISC-based vendors like Qualcomm or other silicon can use Thunderbolt 3 as a high-throughput external connectivity option. This could be a way to establish an even playing field for all of the silicon vendors who are providing processor power for all the various computing devices out there.

At least Intel and AMD are taking steps in the right direction towards the idea of mixing portability and power for computing setups based on regular-computer platforms. It may also make this kind of performance become affordable for most people.
