Zink Enables OpenGL Threading For "Huge Perf Gains"
Zink Enables OpenGL Threading For "Huge Perf Gains"
7 Minutes Ago - Mesa - Zink + glthread - 1 Comment

Recently the open-source AMD OpenGL driver "RadeonSI" enabled OpenGL threading by default for the "glthread" option that has long been opt-in on a per-game/app basis. Along with that has been a number of glthread-related improvements to this code that punts executing OpenGL calls to a separate CPU thread. The Zink OpenGL-on-Vulkan driver has now unconditionally enabled OpenGL threading too.

AMD Ryzen 7 7700X Linux Performance
29 September 11:40 AM EDT - Processors - 16 Comments

Earlier this week I published my AMD Ryzen 9 7900X and Ryzen 9 7950X Linux review as well as an extensive Zen 4 AVX-512 analysis and Linux gaming performance tests. Since then I have received the Ryzen 7 7700X from AMD for Linux testing and out today are those initial Linux benchmarks. The AMD Ryzen 7 7700X is available in-stock at $399 USD from Internet retailers and is an 8-core / 16-thread processor with a maximum boost clock speed of 5.4GHz.

One of the new drivers set to make its debut with Linux 6.1 is the AMD Platform Management Framework "PMF" with an intent on "making AMD PCs smarter, quieter, power efficient by adapting to user behavior and environment" with next-generation hardware. Another part of AMD PMF, the Cool and Quiet Framework (CnQF) has also been queued up for introduction in Linux 6.1.

Revisiting AMD EPYC 7773X "Milan-X" Performance With Linux 6.0 + Ubuntu 22.10
28 September 06:55 AM EDT - Processors - 10 Comments

Earlier this month I revisited the AMD Ryzen 7 5800X3D Linux performance for looking at the effectiveness of the AMD 3D V-Cache under Linux when now using the very latest Linux kernel along with other new/updated benchmarks of the past several months. While already being very impressed by the performance of AMD EPYC Milan-X since those 3D V-Cache server CPUs launched earlier this year, here is a fresh round of Linux benchmarks looking at the EPYC 7763 vs. 7773X performance when running on a development snapshot of Ubuntu 22.10 paired with the Linux 6.0 development kernel and other newer software packages for a very up-to-date look at the performance potential on the server side.

Monday saw the AMD Ryzen 7000 series review embargo lift and retail availability beginning today for those Zen 4 desktop CPUs. Intel meanwhile is using today -- the first day of their second annual Innovation event in San Jose -- to announce 13th Gen Core "Raptor Lake" processors for aiming to take AMD's Zen 4 head-on.

Thanks Microsoft: RadeonSI Enables Async VA-API For Faster Video Acceleration
Thanks Microsoft: RadeonSI Enables Async VA-API For Faster Video Acceleration
27 September 07:33 AM EDT - Mesa - FFmpeg async_depth - 13 Comments

Last week I wrote about how Microsoft landed a VA-API improvement in Mesa to support faster Video Acceleration API encoding with FFmpeg. That code was initially only wired up for the Microsoft D3D12 driver within Mesa for WSL use-cases, but now AMD has taken advantage of the new capability for RadeonSI Gallium3D usage with their Radeon GPUs.

Linux 6.0 Merges The AMD Performance Fix For The Old "Dummy Wait" Workaround
26 September 06:48 PM EDT - AMD - Chipset Workaround - 42 Comments

This morning I called attention to some pending work around a 20 year old chipset workaround in the Linux kernel had been hurting modern AMD systems by erroneously still applying the change to modern hardware. Fortunately, that patch has now been picked up by Linus Torvalds in time for the Linux 6.0 kernel expected for its stable debut next weekend.

AMD Ryzen 9 7900X / Ryzen 9 7950X Benchmarks Show Impressive Zen 4 Linux Performance
26 September 09:00 AM EDT - Processors - 76 Comments

The review embargo just lifted for the AMD Ryzen 7000 series "Zen 4" desktop processors ahead of their retail availability this week. As such there are a few Phoronix articles today looking at these Zen 4 processors under Linux and many benchmarks whole several more follow-up articles will be coming over the weeks ahead. For the launch-day review I have the AMD Ryzen 9 7900X and 7950X processors. Let's take a look at the significant performance improvements to find with the AMD Ryzen 9 7900 series under Linux.

AMD Zen 4 AVX-512 Performance Analysis On The Ryzen 9 7950X
26 September 09:00 AM EDT - Processors - 52 Comments

While much of AMD's briefings for the Ryzen 7000 desktop series were focused on gaming and other consumer workloads, one of the most exciting aspects for me with the Ryzen 7000 series is AMD now supporting AVX-512. But rather going for a 512-bit FPU data path and the possibility of reduced clock frequencies and power/thermal concerns, they employed a 256-bit "double pumping" strategy. When getting the AMD Ryzen 9 7950X in the lab, exploring the AMD Zen 4 AVX-512 performance was one of the areas I was most excited to evaluate. From the benchmarks about to be shown, AMD's initial AVX-512 implementation is promising and has me all the more excited for finding it on AMD EPYC "Genoa" processors.

AMD Ryzen 9 7900X / 7950X Linux Gaming Performance
26 September 09:00 AM EDT - Linux Gaming - 17 Comments

Today the review embargo expires on the AMD Ryzen 7000 series desktop processors ahead of their retail availability this week. Over the past two weeks I have been testing the AMD Ryzen 9 7900X and 7950X processors as the initial review samples (I should be receiving the Ryzen 5 7600X and Ryzen 7 7700X CPUs this week, AMD is staggering their review seeding of the different models). In this article to get things started are my initial Linux gaming benchmarks with the Ryzen 9 7900X/7950X compared to an assortment of other AMD and Intel systems.

A 20 Year Old Chipset Workaround Has Been Hurting Modern AMD Linux Systems
26 September 05:26 AM EDT - AMD - Whoops - 46 Comments

AMD engineer K Prateek Nayak recently uncovered that a ~20 year old chipset workaround in the Linux kernel still being applied to modern AMD systems is responsible in some cases for hurting performance on modern Zen hardware. Fortunately, a fix is on the way for limiting that workaround to old systems and in turn helping with performance for modern systems.
