Like with this (Sony) VAIO Z Series ultraportable, an add-on module with integrated optical disk or other storage could add capabilities to today’s small-form-factor computers

A key trend affecting personal computing is for us to move away from the traditional three-piece desktop computer towards smaller form factors.

Here, the traditional desktop computer’s system unit was a large box that was about the size of a hi-fi component or a large tower. As well the smaller form factors we are heading towards are laptops / notebooks; ultra-small desktop computers of the Intel NUC ilk; or all-in-one

USB-C (also the physical connector for Thunderbolt 3)- the newer connection type that can make better use of add-on modules

which integrate the computing power with the display.

With these setups, it is assumed that we are moving away from on-board data storage in the form of hard disks or staying well clear of packaged media in the form of optical disks. This is driven by online software delivery and the use of streaming audio and video services.

.. with this applying for small-factor desktops like the The Intel Skull Canyon NUCvideo services.

What was often valued about the traditional computer design was that there was extra space to house more storage devices like hard disks or optical drives or the ability to install high-performance graphics cards. This is why these form factors still exist in the form of high-performance “gaming-rig” computers where performance is more important and there is the likely of more data being held on these machines.

But for some of us, we will still want to maintain access to prior storage media types like optical disks or use high-performance graphics chipsets especially at home or our main workspace.  For example, the traditional optical discs are still valued when it comes to media in an always-accessible future-proof collectible form.

There is also the idea of maintaining a secondary hard disk as extra storage capacity specifically for data, whether as a backup or as an offload storage location. This is more so where you are dealing with laptop computers that are equipped with solid-state storage of up to 256Gb and there is a desire to keep most of your data that you aren’t working with somewhere else.

Laptop users often answered this need through the use of a “dock” or expansion module to connect a cluster of peripherals to a single box which has only one connection to the host laptop computer. But Thunderbolt 3 facilitated the rise of external graphics modules which add extra graphics horsepower to laptops and similar low-profile computers.

This concept can be taken further with USB-C or Thunderbolt 3 expansion docks that have integrated optical drives and/or mounting space for hard disks. These would present to the host as Mass Storage devices, using the operating-system class drivers for this kind of device. Of course there would be the expansion abilities for extra USB devices, as well as an Ethernet network interface and/or onboard USB audio chipset with own SP/DIF or analogue connections.

Video to the displays could be facilitated via DisplayPort alt or USB DisplayLink for devices not implementing an external graphics module functionality. In the latter situation, it is like “hotting up” a car for higher performance.

Of course they would have to be self-powered with a strong USB Power Delivery output for the host and USB peripherals. There could be research in to having USB ports head in to optimised charge-only mode when the host computer isn’t active for example.

Most of the onboard devices will be required to represent the devices according to standardised device classes. This will typically lead to a “plug-and-play” setup routine so you aren’t downloading extra software to run the devices if you use recent versions of the main operating systems.

Manufacturers could see these devices as something that complements their ultra-small desktop computer product lines. This is in an approach similar to how consumer hi-fi equipment, typically devices of a particular model range are designed and marketed. Here, the importance would be on having equipment that shares common styling or functional features but encouraging the ability to expand the ultra-small desktop computer at a later date.

The idea here is to allow users to adapt portable or small-form-factor computers to their needs as and when they see fit. It is as long as these computers implement USB 3.1 connections in Type-C form or, for faster throughput and support for external graphics modules, implement Thunderbolt 3 over USB-C connections.

Just lately, as more premium and performance-grade laptops are being equipped with a Thunderbolt 3 connection, the external graphics modules, also known as graphics docks or graphics docking stations, are starting to trickle out on to the market as a performance-boosting accessory for these computers.

The Thunderbolt 3 connection, which uses the USB Type-C plug and socket, is able to provide a throughput similar to a PCI-Express card bus and has put forward a method of improving a laptop’s, all-in-one’s or small-form-factor computer’s graphics ability. This is being facilitated using the external graphics modules or docks that house graphics processors in the external boxes and link these to the host computer using the above connection. What it will mean is that these computers can benefit from desktop-grade or performance-grade graphics without the need to heavily modify them and, in the case of portable computers, can allow for “performance” graphics to be enjoyed at home or in the office while you have battery-conserving baseline graphics on the road,

The devices come in two classes:

• Integrated graphics chipset (Acer Graphics Dock) – devices of this class have a hardwired graphics chipset similar to what is implemented in an all-in-one or small-form-factor computer.
• Card cage (Razer Core, Akitio Node) – These devices are simply a housing where you can install a PCI-Express desktop graphics card of your choice. They have a power supply and interface circuitry to present the desktop graphics card to the host computer via a Thunderbolt 3 connection.

What will they offer?

All these devices will have their own video outputs but will yield what the high-performance graphics chipset provides through the host computer’s integral screen, the video outputs integrated with the host computer as well as their own video outputs. This is in contrast to what used to happen with desktop computers where the video outputs associated with the integrated graphics chipset became useless when you installed a graphics card in these computers.

I have read a few early reviews for the first generation of graphics modules and Thunderbolt-3 laptops. One of these was Acer’s integrated graphics module kitted out with a NVIDIA GTX960M GPU, known to be a modest desktop performer but its mobile equivalent is considered top-shelf for laptop applications. This was ran alongside an Acer TravelMate P658 and an Acer Aspire Switch 12S, with it providing as best as the graphics would allow but highlighting where the weakness was, which was the mobile-optimised Intel Core M processors in the Switch 12S convertible.

Simplified plug-in expansion for all computers

The Intel Skull Canyon NUC can easily be “hotted up” with better graphics when coupled with an external graphics module

Another example was a manufacturer’s blog post about using their “card-cage” graphics dock with one of the Intel Skull Canyon “Next Unit Of Computing” midget computers which was equipped with the Thunderbolt 3 connection. This showed how the computer increased in graphics performance once teamed with the different graphics cards installed in that “card-cage” module.

It opened up the idea of using an “AV system” approach for enhancing small-form-factor and integrated computers. This is where you connect extra modules to these computers to increase their performance just like you would connect a better CD player or turntable or substitute an existing amplifier for something more powerful or plug in some better speakers if you wanted to improve your hi-fi system’s sound quality.

This usage case would earn its keep with an “all-in-one” computer which has the integrated monitor, the aforementioned “Next Unit Of Computing” midget computers or simply a low-profile desktop computer that wouldn’t accommodate high-performance graphics cards.

Software and performance issues can be a real stumbling block

What I had come across from the material I had read was that as long as the host computer had the latest version of the operating system, the latest BIOS and other firmware to support graphics via Thunderbolt 3, and the latest drivers to support this functionality then it can perform at its best. As well, the weakest link can affect the overall performance of the system, which can apply to various mobile system-on-chip chipsets tuned primarily to run cool and allow for a slim lightweight computer that can run on its own batteries for a long time.

At the moment, this product class is still not mature and there will be issues with compatibility and performance with the various computers and external graphics modules.

As well, not all graphics cards will work with every “card-cage” graphics module. This can be due to high-end desktop graphics cards drawing more current than the graphics module can supply, something that can be of concern with lower-end modules that have weaker power supplies, or software issues associated with cards that aren’t from the popular NVIDIA or AMD games-focused lineups. You may have to check with the graphics module’s vendor or the graphics card’s vendor for newer software or firmware to be assured of this compatibility.

Multiple GPUs – a possible reality

A situation that may have to be investigated as more of these products arrive is the concurrent use of multiple graphics processors in the same computer system no matter the interface or vendor. The ability to daisy-chain 6 Thunderbolt-3 devices on the same Thunderbolt-3 connection, along with premium desktop motherboards sporting this kind of connection along with their PCI-Express expansion slots, will make the concept become attractive and easy to implement. Similarly, some vendors could start offering Thunderbolt-3 expansion cards that plug in to existing motherboards’ PCI-Express expansion slots to give existing desktop PCs this functionality.

Here, the goal would be to allow multiple GPUs from different vendors to work together to increase graphics performance for high-end games or multimedia-production tasks like video transcoding or rendering of video or animation projects. Or it could be about improving the performance and efficiency of a multiple-display setup by allocating particular graphics processors to particular displays, something that would benefit larger setups with many screens and, in some cases, different resolutions.

Highly-portable gaming setups being highlighted as a use case

A usage class that was always put forward for these external graphics modules was the teenage games enthusiast who is studying at senior secondary school and is ready to study at university. Here, the usage case underscored the situation where they could be living in student accommodation like a college dorm / residence hall or be living in a share-house with other students.

The application focuses on the use of a laptop computer that can be taken around the campus but be connected to one of these modules when the student is at their home. I would add to this the ability to carry the graphics module between their room and the main lounge area in their home so that they could play their games on the bigger TV screen in that area. This is due to the device being relatively compact and lightweight compared to most desktop computers.

That same application can cover people who are living in accommodation associated with their job and this is likely to change frequently as they answer different work placements. An example of this would be people whose work is frequently away from home for significant amounts of time like those who work on ships, oil rigs or mines. Here, some of these workers may be using their laptop that they use as part of their work during their shift where applicable such as on a ship’s bridge, but use it as a personal entertainment machine in their cabin or the mess room while they are off-shift.

What could be seen more of these devices

Once the external graphics modules mature as a device class, they could end up moving towards two or three classes of device.

One of these would be the integrated modules with graphics chipsets considered modest for desktop use but premium for laptop use. The expansion abilities that these may offer could be in the form of a few extra USB connections, an SD card reader and / or a higher-grade sound module. Perhaps, they may come with an optical drive of some sort. Some manufacturers may offer integrated modules with higher-performance graphics chipsets along with more connections for those of us who want to pay a premium for extra performance and connectivity. These would be pitched towards people who want that bit more “pep” out of their highly-portable or compact computer that has integrated graphics.

Similarly, it could be feasible to offer larger-screen monitors which have discrete graphics chipsets integrated in them. They could also have the extra USB connections and / or secondary storage options, courting those users who are thinking of a primary workspace for their portable computer while desiring higher-performance graphics.

The card-cage variants could open up a class of device that has room for one or two graphics cards and, perhaps, sound cards or functionality-expansion cards. In some cases, this class of device could also offer connectivity and installation options for user-installable storage devices, along with extra sockets for other peripherals. This class of device could, again, appeal to those of us who want more out of the highly-compact computer they started with or that high-performance laptop rather than using a traditional desktop computer for high-performance computing.

Portable or highly-compact computers as a package

Manufacturers could offer laptops, all-in-one and other highly-compact or highly-portable computers that are part of matched-equipment packages where they offer one or more external graphics modules as a deal-maker option or as part of the package. These could differ by graphics chipset and by functionality such as external-equipment connectivity or integrated fixed or removable storage options.

This is in a similar vein to what has happened in the hi-fi trade since the 1970s where manufacturers were offering matched-equipment packages from their lineup of hi-fi components. Here they were able to allow, for example, multiple packages to have the same tape deck, turntable or CD player while each of the package was differentiated with increasingly-powerful amplifiers or receivers driving speakers that had differing levels of audio performance and cabinet size. It still was feasible to offer better and more capable source components with the more expensive packages or allow such devices to be offered as a way to make the perfect deal.

Conclusion

Expect that as more computers equipped with the Thunderbolt 3 over USB-C connection come on the market the external graphics module will become a simplified method of improving these computers’ graphic performance. It will be seen as a way for allowing highly-compact or highly-portable computers to benefit from high-performance graphics at some point in their life, something that this class of computer wouldn’t be able to normally do.

Here’s The Box That Can Turn a Puny Laptop Into a Graphical Powerhouse | Gizmodo

My Comments

The Sony VAIO Z Series ultraportable with functionality expanded by an add-on module

There have been some successful attempts at developing outboard expansion modules or docking stations that add discrete graphics or a better discrete-graphics solution to a laptop computer which wouldn’t have internal room for this kind of performance.

One of these was Sony with their VAIO Z Series that I reviewed previously which had an expansion module that housed a Blu-Ray drive and an AMD discrete graphics chipset. This used an Intel “Light Peak” connection (Thunderbolt over USB) between the devices to provide for high data throughput between the host computer and the expansion module.

Another of these was one of the new Alienware gaming laptops that could connect to a so-called “Graphics Amplifier” which was an expansion module for some of the Alienware R2 series gaming laptops that could house one or two PCI-Express graphics cards. This brought forward the idea that a laptop could have desktop gaming-rig performance just by adding on an expansion module.

Both these solutions implemented manufacturer-specific connection methods which restricted which devices can connect to these “external-graphics” expansion modules.

But the USB 3.1 standard with the Type-C connection allowed the same connection to be used to connect other devices via different logical connection methods like Intel’s Thunderbolt. This was effectively “opened up” as a high-performance connection for expansion modules when Intel launched “Thunderbolt 3” which has throughput equivalent to what happens on a computer’s motherboard.

This led to some reference designs being presented at the Intel Developers Forum 2015 for external-graphics docks of the Sony VAIO Z or Alienware Graphics Amplifier ilk that are able to work with laptops that have the USB Type-C and Intel Thunderbolt 3 connection. In their own right, they are expansion modules which add extra connectivity to the laptop but also they give it access to improved discrete graphics chipsets. One of these was modelled on the Alienware Graphics Amplifier by virtue of allowing the use of fully-fledged graphics cards of the kind expected in that tower-style gaming rig.

The equipment that was shown proved the concept that you could use Thunderbolt 3 over a USB 3.1 Type C physical connection to provide an external discrete-graphics solution for an ultraportable laptop computer or similarly-small computer design. This proves that it can be feasible to use these modules for an “at-home” or “at-office” solutions where performance is desirable but allow for a lightweight computer system.

Similarly, a manufacturer could offer a laptop or all-in-one desktop with the integrated graphics but allow their customers to buy a graphics expansion module at a later date should they want something with more graphics acumen. Here, they can simply plug in the graphics expansion module and play rather than opening up the computer to install a graphics card. There is also a reality that as newer graphics chipsets come along, the person can purchase a newer expansion module or, in the case of those units that use PCI-Express desktop cards, install a newer graphics card in to the module to take advantage of these newer designs.

It simply underscores that fact that USB 3.1 Type C opens up the concept of expandability for tablets, laptops, all-in-one and small-profile desktops even further by use of external modules that offer different functions to suit different needs at different times.

Introduction

The Sony VAIO Z Series ultraportable with functionality expanded by an add-on module

Previously, I reviewed the Sony VAIO Z Series ultra-thin premium laptop and the review sample cam with an expansion module that linked to this laptop with an LightPeak-(Thunderbolt)-via-USB3 connection. This provided discrete graphics circuitry, an Ethernet connection, video outputs, extra USB sockets as well as a slot-load Blu-Ray reader / DVD-burner optical drive. A cheaper variant of this laptop had the expansion module as an optional accessory rather than in the box.

Well, the age of the Ultrabook is here and some of us may want to have these machines benefit from extra connectivity or functionality at our main work locations yet benefit from a lightweight design when out and about.

Most of us would expand these computers with a myriad of adaptors and modules that plug in to these computers’ USB ports and this could yield a mess when you have many of these peripherals and too few USB ports on the computers.

Docking Stations before

Previously, some manufacturers used to supply docking-stations and port-expanders that integrated with some of their laptop lines usually through a proprietary multipin connector. These typically served one main function i.e. to connect larger desktop peripherals to the laptop but allow the user to quickly remove the laptop when they hit the road.

Data connectivity nowadays

Now the USB 3.0 and Thunderbolt connector can make this concept real for most Ultrabook models when it comes to data transfer; and this can work well with setups that just provide access to an optical drive and / or extra connectors.

These connections allow for high-bandwidth data throughput which can support the requirements of Blu-Ray Discs, high-capacity high-throughput hard disks, Gigabit Ethernet, data for discrete-video GPUs serving high-resolution displays or many more USB 2.0 connectors.

A current problem

Expansion unit as a power supply

But there are issues involved if the expansion module is to be a power supply for the portable computer. Here, most manufacturers ask for different input voltage and current levels for their different notebook computer designs, and they also use different DC plug sizes for some of their products.

This can be easier if the goal is to have the device work with one particular make or model-range of computer. But it can be harder if you expect an expansion module to work across a larger range of products such as a manufacturer’s complete lineup or products made by different manufacturers.

If there is an industry expectation that all Ultrabooks and, perhaps, other ultraportable computers, are to have a particular power-supply requirement for outboard chargers, the power-supply functionality could be answered through the provision of a standard flylead from the expansion device to the host computer.

This could be facilitated through the use of a standard power-supply requirement and connection type for portable computer power-supply connections. It can then allow for power-supply innovation by computer manufacturers and third parties to provide power to these computers from different power sources.

What can be provided

Optical disc

These modules could provide an optical disc drive so one can play or burn CDs / DVDs / Blu-Ray Discs with the Ultrabooks. This could come in handy either with entertainment or with installing software held on these discs. In some cases, people could burn data to these discs due to them being sold for a “dime a dozen”.

Extra connections

Another benefit would be to provide increased connection and expansion abilities for the Ultrabook. This would play well for those users who press a 13” laptop as a computing device at their main location, having it hooked up to a large screen and a keyboard and mouse fit for use with a desktop computer as well as some decent speakers or a nice sound system at their main workstation.

Typically this would manifest in extra USB sockets of the 2.0 or 3.0 variety as well as an Ethernet socket for connecting to a Gigabit Ethernet or HomePlug AV network.

Improved video and audio

An expansion module could help a manufacturer raise an Ultrabook’s multimedia credentials whether it is to enjoy creating or playing audio, video or photo content.

If the manufacturer decided to follow Sony’s example, they could house discrete video circuitry in the expansion unit in order to provide for enhanced multimedia-grade graphics. These could service the laptop’s integrated display or a display connected to video terminals on the expansion unit. In some cases, the expansion module could be a display in the order of 21” or more working as a second screen.

Similarly the sound quality available from an Ultrabook could be improved through the use of discrete sound-processing modules like the Creative Labs modules. This could open up paths like analogue RCA inputs and outputs or SP/DIF digital connections (Toslink optical or RCA coaxial) to connect to good-quality sound systems. As well there could be the use of one or more 1/4” jacks that can be used to connect good microphones or musical instruments to this module for recording.

In some cases, this could extend to the integration of broadcast tuners in to these modules to permit an Ultrabook to receive radio or TV broadcasts.

Providing to the market

Manufacturers should be encouraged to provide more than one different expansion module so that customers can choose the right unit to suit their needs and budget rather than just their computer. As well, they can make sure that these units can cover a larger range of their small notebooks. It can also allow for customers to upgrade their notebooks to suit different needs as well as purchasing different expansion modules for different needs at a later date.

Conclusion

Yes, an expansion module for the new class of Ultrabooks can be a viable computer-accessory product and, once worked out properly, could serve a large range of these computers.
