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.

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."

The fourth Radeon Software Crimson Edition graphics driver to be released this month, dated November 15th, was just published on their website. These have not been WHQL certified, like the previous ones, but that might actually be for the best. Rapid graphics driver releases, not throttled by Microsoft red tape, probably increases driver quality over this busy time of year. Also, I recently found out that WHQL certification is not a requirement for clean installed Windows 10 Anniversary Edition systems with Secure Boot Enabled. Both AMD and NVIDIA sign their hotfix drivers in a way that satisfies this check, without going through the entire WHQL process.
That aside, Radeon Software Crimson Edition 16.11.4 rolls in additional fixes to Civilization VI. AMD isn’t saying what these fixes are, such as whether they are for general performance optimizations or stability issues that we haven’t heard about yet, but it’s out now so you should probably update if you are currently playing the game. The driver also fixes problems when attempting to watch web video and play a game simultaneously, which is actually something I do frequently. (Don’t knock listening to podcasts while playing StarCraft II Arcade until you try it...) Thirdly, 16.11.4 also fixes rendering issues in Titanfall 2 that occur while piloting a Titan.

Compared to Q2 2016, total GPU shipments including discrete and integral chips in the mobile and desktop markets increased by 20%; good but not enough to recover to the volume we saw in Q3 2015. Indivdually, total AMD sales increased by 15% and but Intel 18% but it was NVIDIA that was the most successful with a 39% increase. In AMD's case they saw sales of their aging desktop APUs drop by 10% but that was more than offset by a jump in discrete GPU sales of 34.7% and an increase in laptop demand by 19.1% . The discrete GPU market as a whole has grown by 35.6% from the last quarter and by 10.1% when compared to last year. This is not bad news for AMD or Intel but it is certainly NVIDIA who has the most to celebrate. Pop over to Jon Peddie Research for a look at their overview, or check out the full report if you subscribe to them.
Obviously the PC is still dead ... right?

"AMD's overall unit shipments increased 15.38% quarter-to-quarter, Intel's total shipments increased 17.70% from last quarter, and Nvidia's increased 39.31%."

VR offers a variety of new creative opportunities, not simply a new way to make games. For instance StudioDisrupt has created a VR movie called Please State Your Name about a decapitated robot's head in a garbage dump. While the movie has a script which it runs through, you have the freedom to move your perspective around the world. While this may not sound overly interesting, Kyle over at [H]ard|OCP has watched this movie 25 or 30 times this week even before embarking on this review so there must be something to it. Check out their full look at the performance of AMD and NVIDIA cards in this VR movie by following that previous link. A second version of the movie is available for those using their cellphone as a VR headset, somewhat more limited but seeing as how the movie is free you should take the opportunity.
"Please State Your Name is not a game, it is not really an "experience" either, but rather a short film done in a Virtual Reality world, which puts you right in the middle of the story. This genre of VR is where AMD has been putting a lot of its resources. Can we expect the Radeon RX 480 to show us its VR prowess once again?"

On one side of the ring is the RX 480, with 2304 Stream Processors, 32 ROPs and 144 Texture Units. In the opposite corner, at 1280 CUDA Cores, 48 ROPs and 80 Texture Units is the GTX 1060. The two cards retail for between $200 to $250 depending on the features present on the card as well as any sales. [H]ard|OCP tested the two cards head to head, not just raw performance numbers but also the stability of the GPU frequencies. power draw and temperatures. All games were tested at base clocks and at the highest stable overclock and the results were back and forth, in some games AMD pulled ahead while in others NVIDIA was the clear winner. It is worth keeping in mind that these results do not include VR results.
"We take GIGABYTE’s Radeon RX 480 G1 GAMING video card and pit it against a MSI GeForce GTX 1060 GAMING X video card in today’s evaluation. We will overclock both video cards as high as possible and compare performance and find out what both video cards have to offer in the upper $200 price range for gaming."

Tagged: video, the last hope, serious sam vr, rx 480, radeon, Polaris, multi-gpu, liquidvr, amd, affinity
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.

Tagged: graphics drivers, dishonored 2, crimson, amd
Just a handful of days into this busy month for video game companies, and AMD has released their third Radeon Software Crimson Edition drivers for November. 16.11.3, like 16.11.2 and 16.11.1, are not certified by WHQL. From a quality standpoint, Microsoft certification hasn't exactly made a difference over the last year or so. In fact, both graphics vendors rapidly releasing hotfixes between regular WHQL milestones seems to have a better user experience.
Unfortunately, this does mean that users of clean installed Windows 10 1607 with Secure Boot enabled will be missing out. Correction: The drivers are actually signed by Microsoft with the attestation process.
As for the driver itself, 16.11.3 rolls in AMD's optimizations for Dishonored 2. The game goes live in two days, so this should give users an opportunity to find a good time to install and reboot before launch. It also fixes an issue where Valve's Steam client and EA's Origin client would fail when an external GPU, using AMD's X-Connect Technology standard, is detached.
