Today at the AMD Capsaicin & Cream event at GDC 2017, Senior VP of the Radeon Technologies Group, Raja Koduri officially revealed the branding that AMD will use for their next generation GPU products.
While we usually see final product branding deviate from their architectural code names (e.g. Polaris becoming the Radeon RX 460, 470 and 480), AMD this time has decided to embrace the code name for the retail naming scheme for upcoming graphics cards featuring the new GPU – Radeon RX Vega.
However, we didn't just get a name for Vega-based GPUs. Raja also went into some further detail and showed some examples of technologies found in Vega.
First off is the High-Bandwidth Cache Controller found in Vega products. We covered this technology during our Vega architecture preview last month at CES, but today we finally saw a demo of this technology in action.
Essentially, the High-Bandwidth Cache Controller (HBCC) allows Vega GPUs to address all available memory in the system (including things like NVMe SSDs, system DRAM and network storage.) AMD claims that by using the already fast memory you have available on your PC to augment onboard GPU memory (such as HBM2) they will be able to offer less expensive graphics cards that ultimately offer access to much more memory than current graphics cards.
The demo that they showed on stage featured Deus Ex: Mankind Divided running on a system with a Vega GPU running with 2GB of VRAM, and Ryzen CPU. By turning HBCC on, they were able to show a 50% increase in average FPS, and a 100% increase in minimum FPS.
While we probably won't actually see a Vega product with such a small VRAM implementation, it was impressive to see how HBCC was able to dramatically improve the playability of a 2GB GPU on a game that has no special optimizations to take advantage of the High-Bandwidth Cache.
The other impressive demo running on Vega at the Capsaicin & Cream event centered around what AMD is calling Rapid Pack Math.
Rapid Pack Math is an implementation of something we have been hearing and theorizing a lot about lately, the use of FP16 shaders for some graphic effects in games. By using half-precision FP16 shaders instead of the current standard FP32 shaders, developers are able to get more performance out of the same GPU cores. In specific, Rapid Pack Math allows developers to run half-precision FP16 shaders at exactly 2X the speed of traditional standard-precision FP32 shaders.
While the lower precision of FP16 shaders won't be appropriate for all GPU effects, AMD was showing a comparison of their TressFX hair rendering technology running on both standard and half-precision shaders. As you might expect, AMD was able to render twice the amount of hair strands per second, making for a much more fluid experience.
Just like we saw with the lead up to the Polaris GPU launch, AMD seems to be releasing a steady stream of information on Vega. Now that we have the official branding for Vega, we eagerly await getting our hands on these new High-end GPUs from AMD.

At their Capsaicin Siggraph event tonight AMD has announced that what was previously announced as the FireRender rendering engine is being officially launched as AMD Radeon ProRender, and this is becoming open-source as part of AMD's GPUOpen initiative.
From AMD's press release:
AMD today announced its powerful physically-based rendering engine is becoming open source, giving developers access to the source code.
As part of GPUOpen, Radeon ProRender (formerly previewed as AMD FireRender) enables creators to bring ideas to life through high-performance applications and workflows enhanced by photorealistic rendering.
GPUOpen is an AMD initiative designed to assist developers in creating ground-breaking games, professional graphics applications and GPU computing applications with much greater performance and lifelike experiences, at no cost and using open development tools and software.
Unlike other renderers, Radeon ProRender can simultaneously use and balance the compute capabilities of multiple GPUs and CPUs – on the same system, at the same time – and deliver state-of-the-art GPU acceleration to produce rapid, accurate results.
Radeon ProRender plugins are available today for many popular 3D content creation applications, including Autodesk® 3ds Max®, SOLIDWORKS by Dassault Systèmes and Rhino®, with Autodesk® Maya® coming soon. Radeon ProRender works across Windows®, OS X and Linux®, and supports AMD GPUs, CPUs and APUs as well as those of other vendors.

A breakdown of the known specifications for these new GPUs was provided by AnandTech in their report on the WX Series:
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.

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.

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.
