As the first Oculus Rift retail units begin hitting hands in the US and abroad, both AMD and NVIDIA have released new drivers to help gamers ease into the world of VR gaming.
Up first is AMD, with Radeon Software Crimson Edition 16.3.2. It adds support for Oculus SDK v1.3 and the Radeon Pro Duo...for all none of you that have that product in your hands. AMD claims that this driver will offer "the most stable and compatible driver for developing VR experiences on the Rift to-date." AMD tells us that the latest implementation of LiquidVR features in the software help the SDKs and VR games at release take better advantage of AMD Radeon GPUs. This includes capabilities like asynchronous shaders (which AMD thinks should be capitalized for some reason??) and Quick Response Queue (which I think refers to the ability to process without context change penalties) to help Oculus implement Asynchronous Timewarp.
NVIDIA's release is a bit more substantial, with GeForce Game Ready 364.72 WHQL drivers adding support for the Oculus Rift, HTC Vive and improvements for Dark Souls III, Killer Instinct, Paragon early access and even Quantum Break.
For the optimum experience when using the Oculus Rift, and when playing the thirty games launching alongside the headset, upgrade to today's VR-optimized Game Ready driver. Whether you're playing Chronos, Elite Dangerous, EVE: Valkyrie, or any of the other VR titles, you'll want our latest driver to minimize latency, improve performance, and add support for our newest VRWorks features that further enhance your experience.
Today's Game Ready driver also supports the HTC Vive Virtual Reality headset, which launches next week. As with the Oculus Rift, our new driver optimizes and improves the experience, and adds support for the latest Virtual Reality-enhancing technology.
Good to see both GPU vendors giving us new drivers for the release of the Oculus Rift...let's hope it pans out well and the response from the first buyers is positive!

Last week AMD released a new GPU-PRO Beta driver stack and this Monday, NVIDIA released the 364.12 beta driver, both of which support Vulkan and meant that Phoronix had a lot of work to do. Up for testing were the GTX 950, 960, 970, 980, and 980 Ti as well as the R9 Fury, 290 and 285. Logically, they used the Talos Principal test, their results compare not only the cards but also the performance delta between OpenGL and Vulkan and finished up with several OpenGL benchmarks to see if there were any performance improvements from the new drivers. The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.
"Thanks to AMD having released their new GPU-PRO "hybrid" Linux driver a few days ago, there is now Vulkan API support for Radeon GPU owners on Linux. This new AMD Linux driver holds much potential and the closed-source bits are now limited to user-space, among other benefits covered in dozens of Phoronix articles over recent months. With having this new driver in hand plus NVIDIA promoting their Vulkan support to the 364 Linux driver series, it's a great time for some benchmarking. Here are OpenGL and Vulkan atop Ubuntu 16.04 Linux for both AMD Radeon and NVIDIA GeForce graphics cards."

Some Hints as to What Comes Next
On March 14 at the Capsaicin event at GDC AMD disclosed their roadmap for GPU architectures through 2018. There were two new names in attendance as well as some hints at what technology will be implemented in these products. It was only one slide, but some interesting information can be inferred from what we have seen and what was said in the event and afterwards during interviews.
Polaris the the next generation of GCN products from AMD that have been shown off for the past few months. Previously in December and at CES we saw the Polaris 11 GPU on display. Very little is known about this product except that it is small and extremely power efficient. Last night we saw the Polaris 10 being run and we only know that it is competitive with current mainstream performance and is larger than the Polaris 11. These products are purportedly based on Samsung/GLOBALFOUNDRIES 14nm LPP.
The source of near endless speculation online.
In the slide AMD showed it listed Polaris as having 2.5X the performance per watt over the previous 28 nm products in AMD’s lineup. This is impressive, but not terribly surprising. AMD and NVIDIA both skipped the 20 nm planar node because it just did not offer up the type of performance and scaling to make sense economically. Simply put, the expense was not worth the results in terms of die size improvements and more importantly power scaling. 20 nm planar just could not offer the type of performance overall that GPU manufacturers could achieve with 2nd and 3rd generation 28nm processes.
What was missing from the slide is mention that Polaris will integrate either HMB1 or HBM2. Vega, the architecture after Polaris, does in fact list HBM2 as the memory technology it will be packaged with. It promises another tick up in terms of performance per watt, but that is going to come more from aggressive design optimizations and likely improvements on FinFET process technologies. Vega will be a 2017 product.
Beyond that we see Navi. It again boasts an improvement in perf per watt as well as the inclusion of a new memory technology behind HBM. Current conjecture is that this could be HMC (hybrid memory cube). I am not entirely certain of that particular conjecture as it does not necessarily improve upon the advantages of current generation HBM and upcoming HBM2 implementations. Navi will not show up until 2018 at the earliest. This *could* be a 10 nm part, but considering the struggle that the industry has had getting to 14/16nm FinFET I am not holding my breath.
AMD provided few details about these products other than what we see here. From here on out is conjecture based upon industry trends, analysis of known roadmaps, and the limitations of the process and memory technologies that are already well known.

Tagged: vulkan, raja koduri, Polaris, HBM2, hbm, dx12, crossfire, amd
After hosting the AMD Capsaicin event at GDC tonight, the SVP and Chief Architect of the Radeon Technologies Group Raja Koduri sat down with me to talk about the event and offered up some additional details on the Radeon Pro Duo, upcoming Polaris GPUs and more. The video below has the full interview but there are several highlights that stand out as noteworthy.
- Raja claimed that one of the reasons to launch the dual-Fiji card as the Radeon Pro Duo for developers rather than pure Radeon, aimed at gamers, was to “get past CrossFire.” He believes we are at an inflection point with APIs. Where previously you would abstract two GPUs to appear as a single to the game engine, with DX12 and Vulkan the problem is more complex than that as we have seen in testing with early titles like Ashes of the Singularity.
But with the dual-Fiji product mostly developed and prepared, AMD was able to find a market between the enthusiast and the creator to target, and thus the Radeon Pro branding was born.
Raja further expands on it, telling me that in order to make multi-GPU useful and productive for the next generation of APIs, getting multi-GPU hardware solutions in the hands of developers is crucial. He admitted that CrossFire in the past has had performance scaling concerns and compatibility issues, and that getting multi-GPU correct from the ground floor here is crucial.
- With changes in Moore’s Law and the realities of process technology and processor construction, multi-GPU is going to be more important for the entire product stack, not just the extreme enthusiast crowd. Why? Because realities are dictating that GPU vendors build smaller, more power efficient GPUs, and to scale performance overall, multi-GPU solutions need to be efficient and plentiful. The “economics of the smaller die” are much better for AMD (and we assume NVIDIA) and by 2017-2019, this is the reality and will be how graphics performance will scale.
Getting the software ecosystem going now is going to be crucial to ease into that standard.
- The naming scheme of Polaris (10, 11…) has no equation, it’s just “a sequence of numbers” and we should only expect it to increase going forward. The next Polaris chip will be bigger than 11, that’s the secret he gave us.
There have been concerns that AMD was only going to go for the mainstream gaming market with Polaris but Raja promised me and our readers that we “would be really really pleased.” We expect to see Polaris-based GPUs across the entire performance stack.
- AMD’s primary goal here is to get many millions of gamers VR-ready, though getting the enthusiasts “that last millisecond” is still a goal and it will happen from Radeon.
- No solid date on Polaris parts at all – I tried! (Other than the launches start in June.) Though Raja did promise that after tonight, he will only have his next alcoholic beverage until the launch of Polaris. Serious commitment!
- Curious about the HBM2 inclusion in Vega on the roadmap and what that means for Polaris? Though he didn’t say it outright, it appears that Polaris will be using HBM1, leaving me to wonder about the memory capacity limitations inherent in that. Has AMD found a way to get past the 4GB barrier? We are trying to figure that out for sure.
Why is Polaris going to use HBM1? Raja pointed towards the extreme cost and expense of building the HBM ecosystem prepping the pipeline for the new memory technology as the culprit and AMD obviously wants to recoup some of that cost with another generation of GPU usage.
Speaking with Raja is always interesting and the confidence and knowledge he showcases is still what gives me assurance that the Radeon Technologies Group is headed in the correct direction. This is going to be a very interesting year for graphics, PC gaming and for GPU technologies, as showcased throughout the Capsaicin event, and I think everyone should be looking forward do it.

AMD will be the sole GPU presence in the labs at universities participating in Crytek’s VR First initiative, which “provides colleges and universities a ready-made VR solution for developers, students and researchers”, according to AMD.
AMD is leveraging the newly-announced Radeon Pro Duo graphics cards for this partnership, which lends immediate credibility to their positioning of the new GPU for VR development.
“The new labs will be equipped with AMD Radeon™ Pro Duo graphics cards with LiquidVR™ SDK, the world’s fastest VR content creator platform bridging content creation and consumption and offering an astonishing 16 teraflops of compute power. Designed to be compatible with multiple head mounted displays, including the Oculus Rift™ and HTC Vive™, AMD Radeon™ Pro Duo cards will encourage grassroots VR development around the world. The initial VR First Lab at Bahçeşehir University in Istanbul is already up and running in January of this year.”
Crytek CEO Cevat Yerli explains VR First:
“VR First labs will become key incubators for nurturing new talent in VR development and creating a global community well-prepared to innovate in this exciting and emerging field. VR experiences, harnessing the power of the CRYENGINE and developed using world-class Radeon™ hardware and software, will have the potential to fundamentally transform how we interact with technology.”
This certainly appears to be an early win for AMD in VR development, at least in the higher education sector.

It’s finally here, and AMD is ready to ship it, the much discussed and often debated dual-Fiji graphics card that the company first showed with the launch of the Fury series of Radeon cards way back in June of last year. It was unnamed then, and I started calling it the AMD Fury X2, but it seems that AMD has other plans for this massive compute powerhouse, now with a price tag of $1,499.
As part of the company’s Capsaicin event at GDC tonight, AMD showed the AMD Radeon Pro Duo, calling it the “most powerful platform for VR” among other things. The card itself is a dual-slot configuration with what appears to be a (very thick) 120mm self-contained liquid cooler, similar to the Fury X design. You’ll need three 8-pin power connectors for the Radeon Pro Duo as well, but assuming you are investing in this kind of hardware that should be no issue.
Even with the integration of HBM to help minimize the footprint of the GPU and memory system, the Radeon Pro Duo is a bit taller than the standard bracket and is more analogous the length of a standard graphics card.
AMD isn’t telling us much about performance in the early data provided, only mentioning again that the card provides 16 teraflops of compute performance. This is just about double that of the Fury X, single GPU variant released last year; clearly the benefit of water cooling the Pro Duo is that it can run at maximum clock speeds.
Probably the biggest change from what we learned about the dual-GPU card in June to today is its target market. AMD claims that the Radeon Pro Duo is “aimed at all aspects of the VR developer lifestyle: developing content more rapidly for tomorrow’s killer VR experiences while at work, and playing the latest DirectX® 12 experiences at maximum fidelity while off work.” Of course you can use this card for gaming – it will show up in your system just as any dual-GPU configuration would and can be taken advantage of at the same level owning two Fury X cards would.
The Radeon Pro Duo is cooled by a rear-mounted liquid cooler in this photo
That being said, with a price tag of $1,499, it makes very little sense for gamers to invest in this product for gaming alone. Just as we have said about the NVIDIA TITAN line of products, they are the best of the best but are priced to attract developers rather than gamers. In the past AMD had ridiculed NVIDIA for this kind of move but it seems that the math just works here – the dual-Fiji card is likely a high cost, low yield, low production part. Add to that the fact that it was originally promised in Q3 2015, and that AMD has publicly stated that its Polaris-based GPUs would be ready starting in June, and the window for a consumer variant of the Radeon Pro Duo is likely closed.
"The Radeon Pro Duo is AMD's evolution of their high-end graphics card strategy with them positioning the Radeon Pro Duo more towards a content creator audience rather than gamers. This helps justify the higher price and lower volumes as well as gives developers the frame of mind to develop for multi-GPU VR from the get go rather than as an afterthought." - Anshel Sag, Analyst at Moor Insights & Strategy
For engineers, developers, educational outlets and other professional landscapes though, the pure processing power compressed into a single board will be incredibly by useful. And of course, for those gamers crazy enough out there with the unlimited budget and the need to go against our recommendations.
Update: AMD's Capsaicin livestream included some interesting slides on the new Pro Duo GPU, including some of the capabilities and a look at the cooling system.
The industrial design has carried over from the Fury X
As we see from this slide, the Pro Duo offers 2x Fiji GPUs with 8GB of HBM, and boasts 16 TFLOPS of compute power (the AMD Nano offers 8.19 TFLOPS, so this is consistent with a dual-Nano setup).
The cooling system is again a Cooler Master design, with a separate block for each GPU. The hoses have a nice braided cover, and lead to a very thick looking radiator with a pre-attached fan.
From the look of the fan blades this looks like it's designed to move quite a bit of air, and it will need to considering a single (120 mm?) radiator is handling cooling for a pair of high-end GPUs. Temperatures and noise levels will be something to look for when we have hardware in hand.

As part of AMD’s Capsaicin event in San Francisco today, the company is making some bold statements around its strategy for VR, including massive market share dominance, new readiness programs and the future of VR with the Polaris architecture due out this year.
The most surprising statement made by AMD at the event was the claim that “AMD is powering the overwhelming majority of home entertainment VR systems around the world, with an estimated 83 percent market share.” This is obviously not based on discrete GPU sales in the PC market alone, but instead includes the sales of the PlayStation 4 game console, for which Sony will launch its own PlayStation VR headset later this year. (Side note, does JPR not include the array of Samsung phones to be “home entertainment VR” systems?)
There is no denying that Sony's install base with the PS4 has put AMD in the driver seat when it comes to global gaming GPU distribution, but as of today this advantage has not amounted to anything noticeable in the PC space – a stance that AMD was selling hard before the consoles’ launch. I am hesitant to put any weight behind AMD’s PS4 integration for VR moving forward, so the company will have to prove that this is in fact an advantage for the chip maker going into 2016.
AMD is talking up other partnerships as well, including those with HTC and Oculus for their respective headset launches, due in the next 30 days. Beyond that, AMD hardware is being used in the just announced Sulon Q wireless VR headset and has deals in place with various healthcare, media and educational outlets to seed development hardware.
For system vendors and add-in card builders, AMD is launching a certification program that will create labels of “Radeon™ VR Ready Premium” and “Radeon™ VR Ready Creator”. The former will be assigned to graphics cards at Radeon R9 290 performance and above to indicate they are capable of meeting the specifications required by Oculus and HTC for their VR headsets; the latter is going to be assigned only to the Radeon Pro Duo dual-Fiji graphics card, meant to target developers that need maximum performance.
Finally, AMD is showing that its next generation graphics architecture, Polaris, is capable of VR as well.
AMD today demonstrated for the first time ever the company’s forthcoming Polaris 10 GPU running Valve’s Aperture Science Robot Repair demo powered by the HTC Vive Pre. The sample GPU features the recently announced Polaris GPU architecture designed for 14nm FinFET, optimized for DirectX® 12 and VR, and boasts significant architectural improvements over previous AMD architectures including HDR monitor support, industry-leading performance-per-watt 2, and AMD’s 4th generation Graphics Core Next (GCN) architecture.
We are still waiting to see if this is the same silicon that AMD showed at CES, a mainstream part, or if we might be witnessing the first demo of a higher end part, wetting the appetite of the enthusiast community.

AMD is powering the world's first truly self-contained VR solution, the Sulon Q, a wireless headset with a powerful computer built in.
AMD has partnered with Sulon Technologies, an startup based in Toronto, to produce this new headset, which seems to have the potential to disrupt the fledgling VR market. The idea is simple, and unique; unlike existing designs that require a VR-ready PC (Oculus Rift, HTC Vive) or the latest smartphone (GearVR) to work, the Sulon Q VR headset incorporates a full gaming PC inside the headset, allowing for the first actually wireless experience in this young technology's existence.
As Ars Technica notes in their post on the Sulon Q this morning:
"According to the announcement, that 'wear and play' untethered design makes the Sulon Q quite different from competition like the Oculus Rift or SteamVR-powered HTC Vive, which both need a relatively high-end PC to actually generate the images on the headset. With the Sulon Q, the Windows 10 PC hardware is built into the unit, including an expected four-core AMD FX-8800P processor with a Radeon R7 graphics card."
Who wouldn't want to wear an entire PC on their head? Thermal (and other health) concerns aside, just what sort of hardware is under the hood (so to speak)? According to the report published at VideoCardz this morning, it will offer a new AMD FX processor (the FX-8800P) and overall specs that look like they belong more to a gaming laptop than a VR headset.
(Quoting directly from the report on VideoCardz via this Reddit post):
Experiences: VR, AR, and spatial computing Ergonomics Lightweight, comfortable, ergonomically designed all-in-one tether-free form factor
Processors: AMD FX-8800P processor at up to 35W with Radeon R7 Graphics leveraging AMD’s Graphics Core Next architecture 4 compute cores and 8 GPU cores unlocked through Heterogeneous System Architecture (HSA) Sulon Spatial Processing Unit (SPU)

A video for the Sulon Q is also up on YouTube this morning:
The two biggest questions that always accompany any new hardware announcement - how much will it cost, and when is it available - have not been answered just yet. We'll await further information as GDC has just begun, but it seems very safe to say that 2016 will be focused very heavily on VR.
