DRM finally did something good for us; revealing detailed information on AMD's new GPU.  In this case the DRM is a portion of the Linux kernel which interfaces with the GPU and some inquisitive minds dug through the code to find details on Vega, which will be supported by this new version of DRM.

This is still in the realms of rumour, but the source is very good as AMD would not likely enter the wrong specifications into this update.  According to the specs which wccftech compiled from the code, Vega features 64 compute units, each containing 64 GCN stream processors, the 4096 SPs will be split into four Shader Engines.  A little math, based on the stated performance figures of 12.5 TFLOLPS for FP32 and 25 TFLOPS for FP16 operations, the GPU should clock above 1.5GHz.  There were no details on the memory frequency though as it uses HBM2 we know it will have a 2048-bit interface which could lead to some interesting performance numbers.

"Thanks to the latest Linux graphics driver update submitted by AMD we now have detailed specifications of the upcoming Radeon RX Vega GPU. The DRM, Direct Rendering Manager, update to Linux was issued yesterday and it’s the first update to date that adds comprehensive Vega feature support to Linux. No doubt in preparation for Vega’s launch which is expected to take place at the end of the month."

Overclockers Club takes a look at XFX's new RX 580, inside and out as they completely removed the cooler to let you see all the parts.  The card does come overclocked right out of the box, however OCC pushed the card further, hitting 1440MHz on the GPU and 2116MHz for the memory.  That result fell short of the Powercolor Golden Sample card they tested but is still not bad, as XFX is not charging much of a premium over the reference model.  Pop by to see the full results.

"XFX's RX 580 8GB GTS Black Edition card is a factory overclocked card that uses a TrueClock OC of 1405MHz on the core right out of the gate with an OC+ core clock of 1425MHz possible. A total of 8GB of high speed GDDR5 memory is used to handle the textures to make 2560 x 1440 the new resolution target."

AMD Releases Radeon Software Crimson ReLive 17.4.4

Subject: Graphics Cards | April 28, 2017 - 03:32 PM |
Tagged: amd, graphics drivers

The latest graphics driver from AMD, Radeon Software Crimson ReLive 17.4.4, aligns with yesterday’s release of Warhammer 40,000: Dawn of War III. They claim that, when the update is applied to an 8GB Radeon RX 580, users could see a performance gain of up-to 7% under certain conditions (when compared to 17.4.3).

The driver was re-released on April 27th, with the new installer no-longer adding a desktop shortcut to join the Quake Champions beta. I haven’t seen it personally, but OC3D claims that the shortcut pointed to a bit.ly link. I can see why users would be upset; AMD should have added an option in the installer that says something like, “Would you like to check out the Quake Champions beta? Yes, No, Create a Desktop Shortcut for Later” rather than just add stuff to the system. That said, a desktop shortcut is as benign as you can get, and I can also see why AMD wouldn’t think much of it.

That issue aside, the driver also fixes several bugs. One notable entry is, for users with an HDR-compatible display, Mass Effect: Andromeda will now display the correct colors under Windows 10 Creators Update. The most severe fix seems to be for RX 550 users, where the GPU would hard-lock a system after “long periods of time” since the last reboot. It sounds like those users should update to 17.4.4 as soon as convenient.

Radeon Software Crimson ReLive 17.4.4 is available at AMD’s website.

Over at HEXUS you can sit back and watch a video of Robert Duffy from id Software discuss the potential of AMD's Ryzen processors in the next generation of game engines, with some hints about Vega.  He is confident that the team at id will be able to utilize the large core counts of Ryzen processors to enable great performance in 4K and even 8K with the new engine.  He specifically mentioned "framerate improvements, improved realism, and improved AI in games - all from the extra cores and threads available.

They were not able to tease any secret information from him, but the video is worth watching for both those interested in Ryzen or looking for information on what is next from id Software.

Could Vega be just around the corner?

Subject: General Tech | April 26, 2017 - 02:32 PM |
Tagged: amd, Vega, rumours

A Facebook post from AMD Poland has started rumours flying around the interwebs as the implication is we will see it arrive this quarter; though perhaps taking a Facebook post as a verified source may lead to disappointment.  However, there is a bit more evidence than just the post which Digital Trends has displayed, we have seen CompuBench results of a mysterious AMD GPU which is very likely to be Vega.  It will have 64 compute units which translates into 4096 stream processors unless something very strange is going on.  The benchmarks also list two frequencies 1GHz and 1.2GHz which indicates computing performance of 8.2 TFLOPS and 9.8 TFLOPS respectively which puts it in the neighbourhood of the GTX 1080's 8.9 TFLOPS.  That will not necessarily directly translate into gaming performance but does indicate that AMD has a nice surprise in store for us. 

Don't forget to add a bit of salt to your rumour consumption and keep your eyes peeled for more information.

"Of course, it’s entirely possible that someone at AMD Poland spoke out of turn, and so this information should be considered unverified at this point. But there’s other information that seems to confirm an imminent release, such as a Vega GPU showing in CompuBench benchmark results — something that usually happens shortly before a new component is released."

The RX 580 on Linux, locked stock and overclock

Tagged: linux, RX 580, amd, overclocking, Polaris

Phoronix have had a chance to test out the refreshed Polaris RX 580 on the Linux 4.11 kernel and Mesa 17.1-devel, initially the AMDGPU-PRO 17.10 driver update was not included thanks to interesting timing.  The performance deltas are as you would expect, a slight increase in performance that is relative to the increased clock speeds, just as when run on Windows.  They also had a chance to try overclocking the new card, AMD added support for overclocking GCN 1.2 and newer cards on their proprietary Linux driver in 2016.  They managed to increase the core by 6% without running into stability issues however when they overclocked the memory, they saw serious performance decreases.  Check out the steps they tried along with the results from the overlocked GPU here.

"Yesterday I posted the initial Radeon RX 580 Linux benchmarks while now with having more time with this "Polaris Evolved" card I've been able to try out a bit more, like the AMDGPU Linux overclocking support. Here are the ups and downs of overclocking the Radeon graphics card under Linux."

AMD Releases Radeon Software Crimson ReLive 17.4.3

Subject: Graphics Cards | April 21, 2017 - 02:12 AM |
Tagged: amd, graphics drivers

During the lull in game releases, AMD has released a new graphics driver with official, WHQL-certified support for Windows 10 Creators Update. As we’ve discussed in the past, I tend to err on the side of, “If you do a decent job at internal QA and the user can choose to skip a version or three, then rapid release is probably better than sitting around for a Microsoft certificate”. I mean, why not push out fixes as they are available if there’s no obvious downsides?

amd-2016-crimson-relive-logo.png

Every so often, a WHQL version needs to be certified, though, if only to be accepted into Windows Update. Note that I don’t actually know whether this specific driver will be pushed by Microsoft after an update to the Creators Update – it’s just an example of a situation where WHQL matters.

That aside, the release notes for Radeon Software Crimson ReLive 17.4.3 do not state any specific fixes or changes. The main reason for this driver is to support the Creators Update for Windows 10, as well as add support for the new Radeon RX 570 and Radeon RX 580 graphics cards.

Rumor: Intel Expects Coffee Lake and Basin Falls Early

Subject: Processors | April 19, 2017 - 08:00 PM |
Tagged: skylake-x, ryzen, kaby lake x, Intel, Core, coffee lake, amd

According to DigiTimes, Intel is expecting to release several new processors earlier than they had originally planned. That said, there are two issues with this report. The first point, which should be expected, is that it compares internal dates that were never meant to be public. It is not like Intel has changed their advertised roadmap.

The second problem is that it’s somewhat contradicted by Intel’s earlier, public statements.

Intel-logo.png

Their rumor claims that Intel will push up the launch of Basin Falls, which is Skylake-X, Kaby Lake-X, and X299, by about two months (around June). It also claims that Coffee Lake, which was originally scheduled for January 2018, will be released in August 2017. Both of these moves are being attributed to AMD’s new products.

The potential, somewhat, sort-of contradiction comes from a tweet that Intel made back in February. In it, they said that the 8th generation of Core processors are expected for 2H’17. This time frame doesn’t include January, although it only barely includes August, too. If Intel was always planning on launching Coffee Lake for the “back to school” season, then at least that half of DigiTimes’ story would be completely incorrect. On the other hand, if Intel’s tweet was talking about a sampling / paper launch in December, with volume shipment soon to follow, then DigiTimes would be fairly accurate.

We don’t know unless someone at Intel confirms either-or.

As for Skylake-X and Kaby Lake-X, it would be interesting to see them launch at Computex / E3. Previous rumors (also from DigiTimes) that place it in the Gamescom, which is a huge gaming conference in Cologne. Interestingly, this rumor claims that only the four-, six-, eight-, and ten-core models will arrive at the time, with a twelve-core model waiting until the whole line was supposed to launch.

This omission makes me wonder if, in fact, Intel are rushing the launch, but they realize that they cannot get enough good chips to fill out the top-end SKU. In that case, it would make sense to push the smaller and partially-disabled chips out the door, while banking the big chips that can run all twelve cores at a reasonable voltage for some clock rate.

If so, that would, in fact, speak volumes about AMD’s roadmap (and Intel’s opinion of it).
