Last week when launching the AMD EPYC 9005 "Turin" processors, on the same day AOCC 5.0 was quietly released as the newest version of AMD's Zen-focused compiler derived from LLVM/Clang. With not only adding AMD Zen 5 "znver5" support but also additional vectorization improvements and other performance optimizations, I was eager to run some benchmarks of AOCC 5.0 against the open-source GCC and LLVM/Clang compilers. Here are those initial benchmarks using dual AMD EPYC 9755 128-core Zen 5 processors.

Unvanquished Working On OpenGL 4.6 Renderer Support
5 Hours Ago - Linux Gaming - Unvanquished + OpenGL 4.6 - 2 Comments

It's been a while since we have seen anything new to report on Unvanquished as one of the few remaining and promising open-source game projects. The Unvanquished FPS/RTS game has been in development for 12 years now and built atop the Daemon engine that is now a very distant fork from the id Tech 3 engine. The latest now is that Unvanquished has been pushing forward OpenGL 4.6 rendering support.

In addition to NVIDIA engineers being at XDC 2024 in Montreal last week for talking about their Wayland driver plans, there was also a presentation by NVIDIA's Daniel Dadap around current Linux challenges in supporting dynamic display mux hardware on modern laptops with iGPU/dGPU combinations and their hopes for improving the support.

AMD EPYC 9755 DDR5-4800 vs. DDR5-6000 Memory Performance
AMD EPYC 9755 DDR5-4800 vs. DDR5-6000 Memory Performance
14 October 10:45 AM EDT - Memory - 2 Comments

With the newly-launched AMD EPYC 9005 series processors continuing to use Socket SP5, there is drop-in upgrade compatibility for existing EPYC 9004 series motherboards/servers. That's assuming, of course, the vendor provides a BIOS update for enabling the EPYC 9005 series "Turin" support and there may be limitations on the maximum CPU/TDP supported given power/thermal constraints. But in going from EPYC 9004 to EPYC 9005 is also upping the maximum memory speed from DDR5-4800 to DDR5-6000 (or DDR5-6400 in validated configurations). For those trying to weigh the benefits of also upgrading your memory if on an existing EPYC 9004 Genoa/Bergamo server to DDR5-6000, here are some memory performance comparison benchmarks for some reference points.

AMD XDNA Linux Driver Updated As It Nears The Upstream Kernel
12 October 09:21 AM EDT - AMD - AMDXDNA - 10 Comments

Back in January AMD published an open-source XDNA Linux kernel driver for supporting their Ryzen AI NPUs. But it wasn't until July that the formal review process for the AMD XDNA driver began as the necessary prerequisite for getting picked up into the mainline Linux kernel. On Friday the fourth iteration of those patches for review were published as it hopefully is closing in on landing within the mainline kernel.

The IO_uring asynchronous I/O API for Linux is quite novel and has proven performance benefits. With time IO_uring has been adapted to other areas of the kernel like networking and now with a proposal raised by an Arm graphics driver engineer, it could potentially be adapted for use by Direct Rendering Manager (DRM) kernel graphics drivers.

AVX-512 Performance With 256-bit vs. 512-bit Data Path For AMD EPYC 9005 CPUs
