Linux's New "Sheaves" Per-CPU Caching Layer Showing Massive Wins For AMD Performance

13 septembre 2025 à 13:00
Earlier this week I wrote about Sheaves as an opt-in, per-CPU array-based caching layer likely coming for Linux 6.18. The sheaves patches have been queued into the "slab/for-next" Git branch ahead of the Linux 6.18 kernel merge window. Patches posted now by Google are showing the Linux Sheaves code having a massive beneficial impact for large AMD systems...

Intel Loses Another Prominent Linux Engineer - Now Going To NVIDIA

13 septembre 2025 à 02:18
In the past few months at Intel between layoffs / corporate reorganizations and some deciding to pursue job opportunities elsewhere, there have been unfortunate impacts to their Linux engineering resources. Intel over the summer lost some prominent Linux engineering talent and in turn has even led to upstream Linux drivers being orphaned along with other driver maintainers departing and various other staffing changes. Unfortunate for Intel, another notable Linux name has left the company...

Intel i915 vs. Xe Graphics Driver Benchmarks For Meteor Lake: Extra Performance In 2025

12 septembre 2025 à 16:35
Last month I provided a fresh look at the Intel Arc A-Series graphics between the i915 and Xe kernel graphics drivers for Linux systems. The aging i915 driver is the default for the Alchemist GPUs but there is "experimental" support with the modern Xe kernel graphics driver. There were some performance advantages for the Arc A-Series if switching over to that newer driver option. Similarly, there are advantages with Meteor Lake too when moving from the i915 to Xe Linux drivers. Here are benchmarks to quantify that advantage.

Intel Linux Graphics Driver Seeing 2~5% Faster Shader Compilation Times, Up To ~20%

12 septembre 2025 à 15:46
A few days ago I wrote about Intel fixing some Panther Lake Xe3 graphics performance issues ahead of launch. The downside of those performance optimizations for Panther Lake was that they led to longer shader compilation times. The good news though is that some separate improvements were merged now for Mesa 25.3 to help enhance the Intel graphics shader compilation performance...

AMD EPYC 9575F CPUs For GPU/AI Servers Show Leading Performance In Benchmarks

11 septembre 2025 à 14:30
Since the launch of the AMD EPYC 9005 series nearly one year ago, I have performed hundreds of different benchmarks on these EPYC "Turin" processors across a wide range of workloads/disciplines to really terrific performance, power efficiency, and value. AMD EPYC 9005 performs exceptionally well compared to the competition from Intel and ARM CPU vendors. One area though I hadn't explored to this point was how well the AMD EPYC 9005 series performs for serving as the host CPU for GPU/AI servers. That changed as I recently wrapped up some benchmarks exploring that area using the AMD EPYC 9575F and it managed to accelerate past the available competition in proving capable of being the superior host processor for AI servers.
