While VR excitement might have cooled slightly in the enthusiast community, there continues to be innovation and software releases on both the Oculus Rift and HTC Vive that are bringing me back to what I think we believe to be part of the future of PC gaming. Serious Sam VR: The Last Hope was announced at E3 this year and is now available as an early access game on Steam. It is a dual wielding shooter that combines the enemies of the previous games along with the crazy weapons that made the series iconic.
And hey, there is something awesome about using a missile launcher that takes up half the screen.
One interesting technology addition to the game is use of AMD LiquidVR affinity multi-GPU. A Croteam developer recently posted a blog on the GPUOpen.com site talking about the implementation.
We wanted to add LiquidVR Affinity Multi-GPU rendering support to our engine because two GPUs can render the two eye views in almost half the time compared to a single GPU and this would greatly reduce our GPU bottlenecks. Affinity MGPU can either be done in one pass or with a separate pass for each eye, in which case we reap the GPU side benefits while the CPU workload stays the same.
We needed about a week to modify all shaders and to make sure that correct data is set for each eye. Single pass rendering with Affinity Multi-GPU gave us a huge speed improvement on both CPU and GPU from our original VR implementation. In the end, it took us less time to do single pass rendering correctly than it took us to fix all the problems caused by multi pass multi-GPU rendering.
After the interest in the Deus Ex multi-GPU scaling video I thought I would see if the Serious Sam implementation was actually beneficial to gamers.
- Test System
- Core i7-5960X
- X99 MB + 16GB DDR4
- AMD Radeon RX 480 8GB
- Driver: 16.10.2
The test was simple: I found that a single RX 480 could run the game at Medium settings perfectly well, but could it be playable on High with multi-GPU? By adding in a second Radeon RX 480 I was able to bring the performance up by 55% or so, making the VR experience nearly flawless.
It's not perfect scaling, but the benefits of multi-GPU for VR, when properly implemented, are obvious. As more games and experiences are released that require higher compute capability or have in-game settings that allow for better image quality, the ability to scale across GPUs will be a welcome addition to the ecosystem.

The professional card market is a lucrative one. For many years NVIDIA has had a near strangle-hold on it with their Quadro series of cards. Offering features and extended support far beyond that of their regular desktop cards, Quadros became the go-to cards for many professional applications. AMD has not been overlooking this area though and have had a history of professional cards that have also included features and support not seen in the standard desktop arena. AMD has slowly been chipping away at Quadro’s marketshare and they hope that today’s announcement will help further that particular goal.
It has now been around five months since the initial release of the Polaris based graphics cards from AMD. Featuring the 4th generation GCN architecture and fabricated on Samsung’s latest 14nm process, the RX 4x0 series of chips have proven to be a popular option in the sub-$250 range of cards. These products may not have been the slam-dunk that many were hoping from AMD, they have kept the company competitive in terms of power and performance. AMD has also seen a positive impact from the sales of these products on the overall bottom line.
Today AMD is announcing three new professional cards based on the latest Polaris based GPUs. These range in power and performance from a sub 50 watt part up to a very reasonable 130 watts. These currently do not feature the SSD that was shown off earlier this year.
The lowest end offering is the Radeon Pro WX 4100. This is a low profile, single slot card that consumes less than 50 watts. It features 1024 stream units, which is greater than that of the desktop RX 460’s 896. The WX 4100 features 2.4 TFLOPS of performance while the RX 460 is at 2.2 TFLOPS. AMD did not specify exactly what chips were used in the professional cards, but the assumption here is that this one is a fully enabled Polaris 11.
The power consumption of this card is probably the most impressive part. Also of great interest is the DP 1.4 support and the four outputs. Finally the card supports 5K monitors at 60 Hz. This is a small, quiet, and cool running part that features the entire AMD Radeon Enterprise software support of the professional market.
The next card up is the Pro WX 5100. This features a sub 75 watt GPU that runs 1792 stream units. We guess that this chip is a cut down Polaris 10. On the desktop side it is similar to the RX 470, but that particular card features more stream units and a faster clockspeed. The RX 470 is rated at 4.9 TFLOPS while the WX 5100 is at 3.9 TFLOPS. Fewer stream units and a lower clockspeed allow it to hit that sub-75 watt figure.
It supports the same number of outputs as the 4100, but they are full sized DP. The card is full sized but still only single slot due to the very conservative TDP.
The final card is the WX 7100. This is based on the fully enabled Polaris 10 GPU and is physically similar to the RX 480. They both feature 2304 stream units, but the WX 7100 is slightly clocked down from the RX 480 as it features 5.7 TFLOPS of performance vs. 5.8 TFLOPS. The card is rated below 130 watts TDP which is about 20 watts lower than a standard RX 480. AMD did not explain to us how they were able to lower the TDP of this card, but it could be simple binning of parts or an upcoming revision of Polaris 10 to improve thermals.
This card is again full sized but single slot. It features the same 4 DP connectors as the WX 5100 and the full monitor support that the 1.4 standard entails.
These products will see initial availability for this month. Plans may of course change and they will be introduced slightly later. Currently the 7100 and 4100 are expected after the 10th while the 5100 should show up on the 18th.
AMD is also releasing the Radeon Pro Software. This is essentially their professional driver development that improves upon features, stability, and performance over time. AMD aims to release new drivers for this market every 4th Thursday each quarter.
This is certainly an important area for AMD to address with their new cards and this updated software scheme. NVIDIA has made a pretty penny over the years from their Quadro stack due to the extremely robust margins for these cards. The latest generation of AMD Radeon Pro WX cards look to stack up favorably against the latest products from NVIDIA.
The WX 7100 will come in at a $799 price point, while the WX 5100 and WX 4100 will hit $499 and $399 respectively.

Continuing with AMD's attempts, especially since the start of the Crimson Edition line, to release a driver alongside big game releases, the graphics vendor has published Radeon Software Crimson Edition 16.9.2. This one aligns with the Ultimate Edition SKU of Forza Horizon 3 from Microsoft Studios, which unlocks in a little over a day. Standard and Deluxe Edition users will need to wait until Tuesday, the 27th. As always, it rolls in all of the tweaks and fixes that AMD has found prior to the game's general release.
Also, AMD has fixed several issues, according to their pleasantly verbose release notes. Crimson Edition 16.9.2 should resolve crashes that occur in Multi-GPU mode with Ashes of the Singularity in DirectX 12. It should also fix things like mouse pointer corruption on RX 400 series graphics.
You can pick it up from AMD's website, for Windows 7, 8.1, and 10, both 32- and 64-bit versions.

AMD is apparently interested in supporting open-source, professional graphics. For instance, the Blender Foundation is interviewing potential hires based on a potential deal with the CPU and graphics vendor. They have also open-sourced a bunch of technologies through their GPUOpen Initiative, such as the Radeon Rays (formerly FireRays) library.
This time, at IFA 2016, they released the Radeon ProRender, which used to be called FireRender. This is a plug-in for multiple 3D applications to render high-quality, raytraced images. The open-source, third-party renderer is currently available for 3D Studio Max, in beta for Maya, Rhinoceros, and Solidworks, and coming soon for Blender. While Cycles is pretty good, the potential for cross-pollination is interesting for the future of open 3D development.
We can't go wrong with more options.

As of yet, AMD has not delivered the open-source Radeon Vulkan driver originally slated to arrive early this year, instead relying on their current proprietary driver. That has not stopped a team of plucky programmers from creating RADV, utilizing the existing AMDGPU LLVM compiler back-end and Intel's work with Mesa NIR intermediate representation to pass to LLVM IR. You won't get Gallium3D support, ironically RADV is too close to the metal for that to work.
Phoronix just wrapped up testing of the new driver, looking at performance for The Talos Principal and DOTA 2, contrasting the open source driver with the closed source AMDGPU-PRO. RADV is not quite 4k ready but at lower resolutions it proves very competitive.
"With word coming out last week that the RADV open-source Vulkan driver can now render Dota 2 correctly, I've been running some tests the past few days of this RADV Vulkan driver compared to AMD's official (but currently closed-source) Vulkan driver bundled with the AMDGPU-PRO Vulkan driver."

We know pretty much all there is to know about AMD's new Polaris architecture thanks to our Radeon RX 480 review, but AMD is taking the covers off of the lower priced, lower performance products based on the same architecture tonight. We previously covered AMD's launch event in Australia where the company officially introduced the Polaris 10 RX 470 and Polaris 11 RX 460 and talked about the broader specifications. Now, we have a bit more information to share on specifics and release dates. Specifically, AMD's RX 470 will launch on Thursday, August 4th and the RX 460 will launch on the following Monday, August 8th.
First up is the Radeon RX 470, based on the same Polaris 10 GPU as the RX 480, but with some CUs disabled to lower performance and increase yields.
This card is aimed at 1080p gaming at top quality settings with AA enabled at 60 FPS. Obviously that is a very vague statement, but it gives you an idea of what price point and target segment the RX 470 is going after.
The only comparison we have from AMD pits the upcoming RX 470 against the R9 270, where Polaris offers a range from 1.5x to 2.4x improvement in a handful of titles, which include DX12 and Vulkan enabled games, of course.
From a specifications stand point, the RX 470 will include 2048 stream processors running at a base clock of 926 MHz and a rated boost frequency of 1206 MHz. That gives us 4.9 TFLOPS of theoretical peak performance to pair with a 6.6 Gbps memory interface capable of 211 GB/s of peak bandwidth. With a 4GB frame buffer and a 120 watt TDP, the RX 470 should offer some compelling performance in the ~$150 price segment (this price is just a guess on my part... though yields should be better – they can salvage RX 480s – and partners being able to use memory chips that do not have to hit 8 Gbps should help to lower costs).
Going down another step to the Radeon RX 460, AMD is targeting this card at 1080p resolutions at "high" image quality settings. The obvious game categories here are eSports titles like MOBAs, CS: Go, Overwatch, etc.
Again, AMD provides a comparison to other AMD hardware: in this case the R7 260X. You'll find a 1.2x to 1.3x performance improvements in these types of titles. Clearly we want to know where the performance rests against the GeForce line but this comparison seems somewhat modest.
Based on the smaller Polaris 11 GPU, which is a new chip that we have not seen before, the RX 460 features up to 2.2 TFLOPS of computing capability with 896 stream processors (14 CUs enabled out of 16 total in full Polaris 11) running between 1090 MHz and 1200 MHz. The memory system is actually running faster on the RX 460 than the RX 470, though with half the memory bus width at 128-bits. The TDP of this card is sub-75 watts and thus we should find cards that don't require any kind of external power. The RX 460 GPU will be used in desktop cards as well as notebooks (though with lower TDPs and clocks).
The chart below outlines the comparison between the three known Polaris graphics processors.
|RX 480||RX 470||RX 460|
|GPU Clock (Base)||1120 MHz||926 MHz||1090 MHz|
|GPU Clock (Boost)||1266 MHz||1206 MHz||1200 MHz|
|Memory||4 or 8 GB GDDR5||4 or 8 GB GDDR5||2 or 4 GB GDDR5|
|Memory Bandwidth||256 GB/s||211 GB/s||112 GB/s|
|GPU||Polaris 10||Polaris 10||Polaris 11|
There is still much to learn about these new products, most importantly, prices. AMD is still shying away from telling us that important data point. The RX 470 will be on sale and will have reviews on August 4th, with the RX 460 following that on August 8th, so we'll have details and costs in our hands very soon.
It is not clear how many or what kinds of cards we can expect to see on the August 4th and August 8th release days though it would stand to reason that they will be mostly based upon reference designs especially for the RX 460 (though Gamer's Nexus did spot a dual fan Sapphire card).. With that said, we may see custom cooled RX 470 graphics cards because while AMD does technically have a reference design with blower style cooler the company expects most if not all of its partners to go their own direction with this board including their own single and dual fan coolers.
For gamers looking to buy into the truly budget card segment, stay tuned just a little longer!
