Earlier in the month [H]ard|OCP investigated the performance scaling that Intel processors display in DX12, now they have finished their tests on AMD processors. These tests include Async computing information, so be warned before venturing forth into the comments. [H] tested an FX 8370 at 2GHz and 4.3GHz to see what effect this had on the games, the 3GHz tests did not add any value and were dropped in favour of these two turbo frequencies. There are some rather interesting results and discussion, drop by for the details.
"One thing that has been on our minds about the new DX12 API is its ability to distribute workloads better on the CPU side. Now that we finally have a couple of new DX12 games that have been released to test, we spend a bit of time getting to bottom of what DX12 might be able to do for you. And a couple sentences on Async Compute."

History and Specifications
The Radeon Pro Duo had an interesting history. Originally shown as an unbranded, dual-GPU PCB during E3 2015, which took place last June, AMD touted it as the ultimate graphics card for both gamers and professionals. At that time, the company thought that an October launch was feasible, but that clearly didn’t work out. When pressed for information in the Oct/Nov timeframe, AMD said that they had delayed the product into Q2 2016 to better correlate with the launch of the VR systems from Oculus and HTC/Valve.
During a GDC press event in March, AMD finally unveiled the Radeon Pro Duo brand, but they were also walking back on the idea of the dual-Fiji beast being aimed at the gaming crowd, even partially. Instead, the company talked up the benefits for game developers and content creators, such as its 8192 stream processors for offline rendering, or even to aid game devs in the implementation and improvement of multi-GPU for upcoming games.
Anyone that pays attention to the graphics card market can see why AMD would make the positional shift with the Radeon Pro Duo. The Fiji architecture is on the way out, with Polaris due out in June by AMD’s own proclamation. At $1500, the Radeon Pro Duo will be a stark contrast to the prices of the Polaris GPUs this summer, and it is well above any NVIDIA-priced part in the GeForce line. And, though CrossFire has made drastic improvements over the last several years thanks to new testing techniques, the ecosystem for multi-GPU is going through a major shift with both DX12 and VR bearing down on it.
So yes, the Radeon Pro Duo has both RADEON and PRO right there in the name. What’s a respectable PC Perspective graphics reviewer supposed to do with a card like that if it finds its way into your office? Test it of course! I’ll take a look at a handful of recent games as well as a new feature that AMD has integrated with 3DS Max called FireRender to showcase some of the professional chops of the new card.

Tagged: Nintendo, amd
Not a whole lot to go off for this announcement. I mean, hints have been dropped, partners have made announcements, and leaks have surfaced for over a year at this point. The only thing that today brings is a release window: March 2017. The final name, exact specifications, and even whatever the thing is that makes this console different, are all currently unknown. Given that E3 2016 will be the last E3 before release, though, I expect that we will find out all about it in June.
Speaking of announcement dates, though, today is an odd one. Midnight (PST) on a seemingly random Wednesday in April doesn't hold any significance to me. Sure, it aligns with their earnings report for investors. Maybe a release date would help raise their stock price (or buffer its potential fall) but it doesn't mean a whole lot for its fans. Does that matter, though? Maybe not.
While this site is PC-oriented, we do touch on console coverage. When the WiiU launched, Ryan disassembled the console over the course of a five-hour livestream, which was archived YouTube. (He dismantled the Xbox One and PlayStation 4 as well.) We are also interested in how AMD benefits from this whole arrangement. That company is one of the few sources for x86 processors, which gaming consoles have been flocking to, as well as high-end graphics. Combine the two, and you can get a relatively cheap system that is quite competent (for not having a discrete, add-in graphics card) at gaming workloads. According to AMD's previous earnings call, they secured multiple design wins, but we'll need to wait and see whether this is one, and whether it includes the CPU this time. As an aside, Nintendo also recently joined the Khronos Group, so that could eventually be interesting for our readers, too... or not.

Tagged: Wraith, Godavari, GLOBALFOUNDRIES, FM2+, amd, X4 880K
Remember that FM2+ refresh which Josh informed you about back in March? The APUs have started arriving on test benches and can be benchmarked independently to see what this ~$100 processor and the Wraith cooler are capable of. Neoseeker compares the new 880K against the older FX-4350 in a long series of benchmarks which show the 880K to be the better part in most cases. There are some interesting exceptions to this, in which the FX-4350's slightly higher frequency allows it to pull ahead by a small margin so there are cases where the less expensive chip would make sense. Read the full review to see which chip makes more sense for you.
"Today we take a look at the AMD Athlon X4 880K, a quad-core FM2+ processor with 4.0/4.2GHz base/Turbo clocks and unlocked multiplier priced at under $100 USD. It's designed for enthusiasts on a budget looking for the fastest multi-core Athlon processor yet without any integrated GPU to add to the cost. It even shares the 95W TDP of AMD's higher-end APUs for optimized power consumption that further leads to more overclocking headroom."

Tagged: graphics driver, crimson, amd
AMD's new Crimson driver has just been released with new features including official support for the new Radeon Pro Duo as well as both the Oculus Rift and HTC Vive VR headsets. It also adds enhanced support for AMD's XConnect technology for external GPUs connected via a Thunderbolt 3 interface. Crossfire profile updates include Hitman, Elite Dangerous and Need for Speed and they have also resolved the ongoing issue with the internal update procedure not seeing the newest drivers. If you are having issues with games crashing to desktop on launch you will still need to disable the AMD Gaming Evolved overlay, unfortunately.
"The latest version of Radeon Software Crimson Edition is here with 16.4.2. With this version, AMD delivers many quality improvements, updated/introduced new CrossFire profiles and delivered full support for AMD’s XConnect technology (including plug’n’play simplicity for Thunderbolt 3 eGFX enclosures configured with Radeon R9 Fury, Nano or 300 Series GPUs.) Best of all, our DirectX 12 leadership continues to be strong, as shown by the performance numbers below."
The Dual-Fiji Card Finally Arrives
This weekend, leaks of information on both WCCFTech and VideoCardz.com have revealed all the information about the pending release of AMD’s dual-GPU giant, the Radeon Pro Duo. While no one at PC Perspective has been briefed on the product officially, all of the interesting data surrounding the product is clearly outlined in the slides on those websites, minus some independent benchmark testing that we are hoping to get to next week. Based on the report from both sites, the Radeon Pro Duo will be released on April 26th.
AMD actually revealed the product and branding for the Radeon Pro Duo back in March, during its live streamed Capsaicin event surrounding GDC. At that point we were given the following information:
- Dual Fiji XT GPUs
- 8GB of total HBM memory
- 4x DisplayPort (this has since been modified)
- 16 TFLOPS of compute
- $1499 price tag
The design of the card follows the same industrial design as the reference designs of the Radeon Fury X, and integrates a dual-pump cooler and external fan/radiator to keep both GPUs running cool.
Based on the slides leaked out today, AMD has revised the Radeon Pro Duo design to include a set of three DisplayPort connections and one HDMI port. This was a necessary change as the Oculus Rift requires an HDMI port to work; only the HTC Vive has built in support for a DisplayPort connection and even in that case you would need a full-size to mini-DisplayPort cable.
The 8GB of HBM (high bandwidth memory) on the card is split between the two Fiji XT GPUs on the card, just like other multi-GPU options on the market. The 350 watts power draw mark is exceptionally high, exceeded only by AMD’s previous dual-GPU beast, the Radeon 295X2 that used 500+ watts and the NVIDIA GeForce GTX Titan Z that draws 375 watts!
Here is the specification breakdown of the Radeon Pro Duo. The card has 8192 total stream processors and 128 Compute Units, split evenly between the two GPUs. You are getting two full Fiji XT GPUs in this card, an impressive feat made possible in part by the use of High Bandwidth Memory and its smaller physical footprint.
|Radeon Pro Duo||R9 Nano||R9 Fury||R9 Fury X||GTX 980 Ti||TITAN X||GTX 980||R9 290X|
|GPU||Fiji XT x 2||Fiji XT||Fiji Pro||Fiji XT||GM200||GM200||GM204||Hawaii XT|

|Transistor Count||8.9B x 2||8.9B||8.9B||8.9B||8.0B||8.0B||5.2B||6.2B|
The Radeon Pro Duo has a rated clock speed of up to 1000 MHz. That’s the same clock speed as the R9 Fury and the rated “up to” frequency on the R9 Nano. It’s worth noting that we did see a handful of instances where the R9 Nano’s power limiting capability resulted in some extremely variable clock speeds in practice. AMD recently added a feature to its Crimson driver to disable power metering on the Nano, at the expense of more power draw, and I would assume the same option would work for the Pro Duo.

Tagged: amd, Zen, China, chinese, licensing
As part of its earnings release today, it was announced that AMD has partnered with a combination of public and private Chinese companies to license its high-end server architecture and products. The Chinese company is called THATIC, Tianjin Haiguang Advanced Technology Investment Co. Ltd., and it will license x86 designs and SoC technology providing all the tools needed to make a server platform including CPUs, interconnects and controllers.
This move is important and intriguing in several ways. First, for AMD, this could be a step to get the company and its products some traction and growth after falling well behind Intel's Xeon platforms in the server space. Increasing the market share of AMD technology, in nearly any capacity, is a move the company needs to have any chance to return to profitability. For the Chinese government, it finally will get access to the x86 architecture, though not in the form of its own license.
By licensing the x86 designs to THATIC, AMD could create an entire host of competitors for itself as well as for Intel, which won't help Intel's in-roads into the Chinese markets for enterprise tech. Intel does not license out x86 technology at all, deciding instead to keep it completely in-house in hopes of being the single provider of processors for devices from the cloud to the smartphone.
The first products built by THATIC will likely use the upcoming Zen architecture, due out in early 2017. AMD creates an interesting space for itself with this partnership - the company will sell its own Zen-based chips that could compete with the custom designs the Chinese organization builds. It's possible that a non-compete of sales based on region is part of the arrangement.
Out of the gate, AMD expects to make $293 million from the deal as part of the joint-venture and also will make money based on royalties. That's great news for a company just posted another net loss for Q1 2016.

Tagged: sony, ps4, Playstation, neo, giant bomb, APU, amd
Based on a new report coming from Giant Bomb, Sony is set to release a new console this year with upgraded processing power and a focus on 4K capabilities, code named NEO. We have been hearing for several weeks that both Microsoft and Sony were planning partial generation upgrades but it appears that details for Sony's update have started leaking out in greater detail, if you believe the reports.
Giant Bomb isn't known for tossing around speculation and tends to only report details it can safely confirm. Austin Walker says "multiple sources have confirmed for us details of the project, which is internally referred to as the NEO."
The current PlayStation 4 APU
Image source: iFixIt.com
There are plenty of interesting details in the story, including Sony's determination to not split the user base with multiple consoles by forcing developers to have a mode for the "base" PS4 and one for NEO. But most interesting to us is the possible hardware upgrade.
The NEO will feature a higher clock speed than the original PS4, an improved GPU, and higher bandwidth on the memory. The documents we've received note that the HDD in the NEO is the same as that in the original PlayStation 4, but it's not clear if that means in terms of capacity or connection speed.
Games running in NEO mode will be able to use the hardware upgrades (and an additional 512 MiB in the memory budget) to offer increased and more stable frame rate and higher visual fidelity, at least when those games run at 1080p on HDTVs. The NEO will also support 4K image output, but games themselves are not required to be 4K native.
Giant Bomb even has details on the architectural changes.
|Shipping PS4||PS4 "NEO"|
|CPU||8 Jaguar Cores @ 1.6 GHz||8 Jaguar Cores @ 2.1 GHz|
|GPU||AMD GCN, 18 CUs @ 800 MHz||AMD GCN+, 36 CUs @ 911 MHz|
|Stream Processors||1152 SPs ~ HD 7870 equiv.||2304 SPs ~ R9 390 equiv.|
|Memory||8GB GDDR5 @ 176 GB/s||8GB GDDR5 @ 218 GB/s|
(We actually did a full video teardown of the PS4 on launch day!)
If the Compute Unit count is right from the GB report, then the PS4 NEO system will have 2,304 stream processors running at 911 MHz, giving it performance nearing that of a consumer Radeon R9 390 graphics card. The R9 390 has 2,560 SPs running at around 1.0 GHz, so while the NEO would be slower, it would be a substantial upgrade over the current PS4 hardware and the Xbox One. Memory bandwidth on NEO is still much lower than a desktop add-in card (218 GB/s vs 384 GB/s).
Could Sony's NEO platform rival the R9 390?
If the NEO hardware is based on Grenada / Hawaii GPU design, there are some interesting questions to ask. With the push into 4K that we expect with the upgraded PlayStation, it would be painful if the GPU didn't natively support HDMI 2.0 (4K @ 60 Hz). With the modularity of current semi-custom APU designs it is likely that AMD could swap out the display controller on NEO with one that can support HDMI 2.0 even though no consumer shipping graphics cards in the 300-series does so.
It is also POSSIBLE that NEO is based on the upcoming AMD Polaris GPU architecture, which supports HDR and HDMI 2.0 natively. That would be a much more impressive feat for both Sony and AMD, as we have yet to see Polaris released in any consumer GPU. Couple that with the variables of 14/16nm FinFET process production and you have a complicated production pipe that would need significant monitoring. It would potentially lower cost on the build side and lower power consumption for the NEO device, but I would be surprised if Sony wanted to take a chance on the first generation of tech from AMD / Samsung / Global Foundries.
However, if you look at recent rumors swirling about the June announcement of the Radeon R9 480 using the Polaris architecture, it is said to have 2,304 stream processors, perfectly matching the NEO specs above.
New features of the AMD Polaris architecture due this summer
There is a lot Sony and game developers could do with roughly twice the GPU compute capability on a console like NEO. This could make the PlayStation VR a much more comparable platform to the Oculus Rift and HTC Vive though the necessity to work with the original PS4 platform might hinder the upgrade path.
The other obvious use is to upgrade the image quality and/or rendering resolution of current games and games in development or just to improve the frame rate, an area that many current generation consoles seem to have been slipping on.
In the documents we’ve received, Sony offers suggestions for reaching 4K/UltraHD resolutions for NEO mode game builds, but they're also giving developers a degree of freedom with how to approach this. 4K TV owners should expect the NEO to upscale games to fit the format, but one place Sony is unwilling to bend is on frame rate. Throughout the documents, Sony repeatedly reminds developers that the frame rate of games in NEO Mode must meet or exceed the frame rate of the game on the original PS4 system.
There is still plenty to read in the Giant Bomb report, and I suggest you head over and do so. If you thought the summer was going to be interesting solely because of new GPU releases from AMD and NVIDIA, it appears that Sony and Microsoft have their own agenda as well.
