Ryan was not the only one at AMD's Radeon Instinct briefing, covering their shot across NVIDIA's HPC products. The Tech Report just released their coverage of the event and the tidbits which AMD provided about the MI25, MI8 and MI6; no relation to a certain British governmental department. They focus a bit more on the technologies incorporated into GEMM and point out that AMD's top is not matched by an NVIDIA product, the GP100 GPU does not come as an add-in card. Pop by to see what else they had to say.
"Thus far, Nvidia has enjoyed a dominant position in the burgeoning world of machine learning with its Tesla accelerators and CUDA-powered software platforms. AMD thinks it can fight back with its open-source ROCm HPC platform, the MIOpen software libraries, and Radeon Instinct accelerators. We examine how these new pieces of AMD's machine-learning puzzle fit together."

AMD Enters Machine Learning Game with Radeon Instinct Products
NVIDIA has been diving in to the world of machine learning for quite a while, positioning themselves and their GPUs at the forefront on artificial intelligence and neural net development. Though the strategies are still filling out, I have seen products like the DIGITS DevBox place a stake in the ground of neural net training and platforms like Drive PX to perform inference tasks on those neural nets in self-driving cars. Until today AMD has remained mostly quiet on its plans to enter and address this growing and complex market, instead depending on the compute prowess of its latest Polaris and Fiji GPUs to make a general statement on their own.
The new Radeon Instinct brand of accelerators based on current and upcoming GPU architectures will combine with an open-source approach to software and present researchers and implementers with another option for machine learning tasks.
The statistics and requirements that come along with the machine learning evolution in the compute space are mind boggling. More than 2.5 quintillion bytes of data are generated daily and stored on phones, PCs and servers, both on-site and through a cloud infrastructure. That includes 500 million tweets, 4 million hours of YouTube video, 6 billion google searches and 205 billion emails.
Machine intelligence is going to allow software developers to address some of the most important areas of computing for the next decade. Automated cars depend on deep learning to train, medical fields can utilize this compute capability to more accurately and expeditiously diagnose and find cures to cancer, security systems can use neural nets to locate potential and current risk areas before they affect consumers; there are more uses for this kind of network and capability than we can imagine.

Third annual release
For the past two years, AMD has made a point of releasing one major software update to Radeon users and gamers annually. In 2014 this started with Catalyst Omega, a dramatic jump in performance, compatibility testing and new features were the story. We were told that for the first time in a very long while, and admitting this was the most important aspect to me, AMD was going to focus on building great software with regular and repeated updates. In 2015 we got a rebrand along with the release: Radeon Software Crimson Edition. AMD totally revamped the visual and user experience of the driver software, bringing into the modern world of style and function. New features and added performance were also the hallmarks of this release, with a stronger promise to produce more frequent drivers to address any performance gaps, stability concerns and to include new features.
For December 2016 and into the new year, AMD is launching the Radeon Software Crimson ReLive Edition driver. While the name might seem silly, it will make sense as we dive into the new features.
While you may have seen the slides leak out through some other sites over the past 48 hours, I thought it was worth offering my input on the release.
Not a performance focused story
The first thing that should be noted with the ReLive Edition is that AMD isn’t making any claims of substantially improved performance. Instead, the Radeon Technologies Group software team is dedicated to continued and frequent iterations that improve performance gradually over time.
As you can see in the slide above, AMD is showing modest 4-8% performance gains on the Radeon RX 480 with the Crimson ReLive driver, and even then, its being compared to the launch driver of 16.6.2. That is significantly lower than the claims made in previous major driver releases. Talking with AMD about this concern, it told us that they don’t foresee any dramatic, single large step increases in performance going forward. The major design changes that were delivered over the last several years, starting with a reconstruction of the CrossFire system thanks to our testing, have been settled. All we should expect going forward is a steady trickle of moderate improvements.
(Obviously, an exception may occur here or there, like with a new game release.)
Radeon ReLive Capture and Streaming Feature
So, what is new? The namesake feature for this driver is the Radeon ReLive application that is built in. ReLive is a capture and streaming tool that will draw obvious comparisons to what NVIDIA has done with GeForce Experience. The ReLive integration is clean and efficient, well designed and seems easy to use in my quick time with it. There are several key capabilities it offers.
First, you can record your gameplay with the press of a hotkey; this includes the ability to record and capture the desktop as well. AMD has included a bevy of settings for your captures to adjust quality, resolution, bitrate, FPS and more.
ReLive supports resolutions up to 4K30 with the Radeon R9 series of GPUs and up to 1440p30 with the RX 480/470/460. That includes both AVC H.264 and HEVC H.265.
Along with recording is support for background capture, called Instant Replay. This allows the gamer to always record in the background, up to 20 minutes, so you can be sure you capture amazing moments that happen during your latest gaming session. Hitting a hotkey will save the clip permanently to the system.

[H]ard|OCP have spent a lot of with Watch Dogs 2 recently, enough to create three articles covering the game of which two are now published. The first article focuses on performance at ultra settings and finding the highest playable settings that the GPUs they tested were capable of, without installing the high resolution texture pack. As it turns out, the game is much more graphically demanding than many other recent releases, so much so that only the Titan X and GTX 1080 was able to perform at 4k resolutions, the GTX 1070 and 1060, as well as the RX 480 and 470 only feature at lower resolutions.
The second article looks at performance with the texture pack installed, which did not have much effect on overall performance but significantly increased VRAM usage. Even the mighty Titan X struggled with this game, we will need a new generation of GPUs to utilize all the available graphics features available in this game. The last review will be up soon and will focus on what effect each of the graphical settings have on the visual appearance of the game.
"Watch Dogs 2 has been released on the PC. We will have a three part evaluation of performance and image quality starting today with performance comparisons. We will also find the highest playable settings for each graphics card and the gameplay experience delivered. Finally, a graphically demanding game."

Tagged: amd, Zen, Summit Ridge
Guru3D got hold of a product list, which includes entries for AMD’s upcoming Zen architecture.
Four SKUs are thus rumored to exist:
- Zen SR3: (65W, quad-core, eight threads, ~$150 USD)
- Zen SR5: (95W, hexa-core, twelve threads, ~$250 USD)
- Zen SR7: (95W, octo-core, sixteen threads, ~$350 USD)
- Special Zen SR7: (95W, octo-core, sixteen threads, ~$500 USD)
The sheet also states that none of these are supposed to contain integrated graphics, like we see on the current FX line. There is some merit to using integrated GPUs for specific tasks, like processing video while the main GPU is busy or doing a rapid, massively parallel calculation without the latency of memory copies, but AMD is probably right to not waste resources, such as TDP, fighting our current lack of compatible software and viable use cases for these SKUs.

The sheet also contains benchmarks for Cinebench R15. While pre-rendered video is a task that really should be done on GPUs at this point, especially with permissive, strong, open-source projects like Cycles, they do provide a good example of multi-core performance that scales. In this one test, the Summit Ridge 7 CPU ($350) roughly matches the Intel Core i7-6850K ($600), again, according to this one unconfirmed benchmark. It doesn’t list clock rates, but other rumors claim that the top-end chip will be around 3.2 GHz base, 3.5 GHz boost at stock, with manual overclocks exceeding 4 GHz.
These performance figures suggest that Zen will not beat Skylake on single-threaded performance, but it might be close. That might not matter, however. CPUs, these days, are kind-of converging around a certain level of per-thread performance, and are differentiating with core count, price, and features. Unfortunately, there doesn’t seem to have been many leaks regarding enthusiast-level chipsets for Zen, so we don’t know if there will be compelling use cases yet.
Zen is expected early in 2017.

Tagged: amd, graphics drivers
For tomorrow’s Watch_Dogs 2, AMD has released Radeon Software Crimson Edition 16.11.5 graphics drivers, giving users a day to configure their PCs. Note that, while the download links in the release notes say 16.11.4, hovering your mouse over them shows the correct version, dated last Friday. Don’t worry, though, the Radeon Technologies Group is based out of Markham, Ontario, Canada, so they didn’t miss out on turkey leftovers to bring you this software.
Okay, yes, that joke was lame. Moving on.
Beyond Watch_Dogs 2, this driver release also adds a new CrossFire profile for Dishonored 2 for Windows 8.x and Windows 10, so multiple GPU users of that game might want to upgrade, too. Beyond that, flickering in The Division and Battlefield 1 while using CrossFire is also addressed.
There are quite a few known issues, though, including a few crashes when using the Vulkan API. Most of these known issues were present in 16.11.4 from a couple of weeks ago, including the aforementioned Vulkan crashes, but this driver adds two. The CrossFire profile for Dishonored 2 that was added with this driver will be disabled on Windows 7, although it sounds like that will be fixed in a future release. Also, Watch_Dogs 2 may flicker or crash when using Crossfire with two RX 480s, but apparently not other configurations.
The driver is not signed by WHQL, but I think I prefer what AMD’s doing now, rapidly releasing several drivers a month, addressing issues as they arise, versus a Microsoft stamp of approval. All that matters is that they can be installed on Anniversary Edition clean installs with Secure Boot enabled, and they can.

[H]ard|OCP sat down with the new DX12 based Gears of War 4 to test the performance of the game on a variety of cards, with a focus on the effect of enabling Async Compute. In their testing they found no reason for Async Compute to be disabled as it did not hurt the performance of any card. On the other hand NVIDIA's offerings do not benefit in any meaningful way from the feature and while AMD's cards certainly did, it was not enough to allow you to run everything at maximum on an RX 480. Overall the game was no challenge to any of the cards except perhaps the RX 460 and the GTX 1050 Ti. When playing at 4K resolution they saw memory usage in excess of 6GB, making the GTX 1080 the card for those who want to play with the highest graphical settings. Get more details and benchmarks in their full review.
"We take Gears of War 4, a new Windows 10 only game supporting DX12 natively and compare performance with seven video cards. We will find out which one provides the best experience at 4K, 1440p, and 1080p resolutions, and see how these compare to each other. We will also look specifically at the Async Compute feature."
