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.

Testing the community developed RADV driver against AMDGPU-PRO

Tagged: amd, radeon, open source, linux, RADV, graphics driver

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."

AMD Details the RX 470 and RX 460 Graphics Cards, Coming in August

Subject: Graphics Cards | July 29, 2016 - 01:09 AM |
Tagged: rx 470, rx 460, radeon, polaris 11, polaris 10, Polaris, amd

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.

slides-25.jpg

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. 

slides-15.jpg

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.

slides-17.jpg

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.

slides-28.jpg

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).

slides-19.jpg

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.

slides-21.jpg

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. 

slides-29.jpg

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
Stream Processors 2304 2048 896
Compute Units 36 32 14
TMUs 144 128 56
ROPs 32 32 16
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 Bus 256-bit 256-bit 128-bit
Memory Bandwidth 256 GB/s 211 GB/s 112 GB/s
TDP 150W 120W <75W
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!

Radeon Software 16.7.1 Adjustments

Last week we posted a story that looked at a problem found with the new AMD Radeon RX 480 graphics card’s power consumption. The short version of the issue was that AMD’s new Polaris 10-based reference card was drawing more power than its stated 150 watt TDP and that it was drawing more power through the motherboard PCI Express slot that the connection was rated for. And sometimes that added power draw was significant, both at stock settings and overclocked. Seeing current draw over a connection rated at just 5.5A peaking over 7A at stock settings raised an alarm (validly) and our initial report detailed the problem very specifically.

AMD responded initially that “everything was fine here” but the company eventually saw the writing on the wall and started to work on potential solutions. The Radeon RX 480 is a very important product for the future of Radeon graphics and this was a launch that needs to be as perfect as it can be. Though the risk to users’ hardware with the higher than expected current draw is muted somewhat by motherboard-based over-current protection, it’s crazy to think that AMD actually believed that was the ideal scenario. Depending on the “circuit breaker” in any system to save you when standards exists for exactly that purpose is nuts.

powertesting.jpg

Today AMD has released a new driver, version 16.7.1, that actually introduces a pair of fixes for the problem. One of them is hard coded into the software and adjusts power draw from the different +12V sources (PCI Express slot and 6-pin connector) while the other is an optional flag in the software that is disabled by default.

Reconfiguring the power phase controller

The Radeon RX 480 uses a very common power controller (IR3567B) on its PCB to cycle through the 6 power phases providing electricity to the GPU itself. Allyn did some simple multimeter trace work to tell us which phases were connected to which sources and the result is seen below.

rx480-phases.jpg

The power controller is responsible for pacing the power coming in from the PCI Express slot and the 6-pin power connection to the GPU, in phases. Phases 1-3 come in from the power supply via the 6-pin connection, while phases 4-6 source power from the motherboard directly. At launch, the RX 480 drew nearly identical amounts of power from both the PEG slot and the 6-pin connection, essentially giving each of the 6 phases at work equal time.

That might seem okay, but it’s far from the standard of what we have seen in the past. In no other case have we measured a graphics card drawing equal power from the PEG slot as from an external power connector on the card. (Obviously for cards without external power connections, that’s a different discussion.) In general, with other AMD and NVIDIA based graphics cards, the motherboard slot would provide no more than 50-60 watts of power, while any above that would come from the 6/8-pin connections on the card. In many cases I saw that power draw through the PEG slot was as low as 20-30 watts if the external power connections provided a lot of overage for the target TDP of the product.
