As another interesting AMD announcement this week following their Advancing AI event yesterday where they launched the EPYC 9005 series and other new hardware, they've continued with a few more soft announcements in the lead-up to the OCP Global Summit happening next week. The latest interesting tid-bit is their plans to incorporate Project Caliptra into their products beginning in 2026.
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.
Now past the launch day for the AMD EPYC 9005 series server processors and having delivered initial AMD EPYC Zen 5 benchmarks for the EPYC 9575F / EPYC 9755 / EPYC 9965 SKUs, it's onto one of my favorite areas of testing and that is the more focused benchmarks looking at different specific changes/features of new processors. Today under the benchmarking microscope is looking at the new AVX-512 512-bit data path capabilities of 5th Gen AMD EPYC compared to using a 256-bit data path or disabling AVX-512 entirely.
The drm-xe-next pull request earlier this week began preparing open-source driver support for Intel Xe3 graphics to premiere with Panther Lake processors. That code is beginning to queue for the upcoming Linux 6.13 cycle. Today a drm-intel-next pull request was sent out to prepare for more Intel Linux kernel graphics driver changes for Linux 6.13.
DRM_Log is an effort that continues to be worked on by Jocelyn Falempe at Red Hat as a new boot logger for printing the kernel messages on the screen.
With 5th Gen AMD EPYC "Turin" processors now launched, AMD provided a same-day release of their updated AMD Optimizing C/C++ Compiler "AOCC". This is AMD's downstream version of LLVM/Clang/Flang where they provide optimized AMD processor support with code that hasn't yet worked its way up into LLVM proper.
Back in August I wrote about AMD beginning work on a new Linux driver to help with heterogeneous core CPUs. On Thursday a second iteration of the AMD HFI Linux driver patches were posted with this driver continuing to work its way toward the mainline kernel.

Last month Intel introduced their Xeon 6 "Granite Rapids" processors with up to 128 P cores, MRDIMM support, and other improvements as a big step-up in performance and power efficiency for their server processors. The Xeon 6900P series showed they could tango with the AMD EPYC 9004 Genoa/Bergamo processors in a number of areas, but Genoa has been around since November 2022... With today's AMD 5th Gen EPYC "Turin" launch, Zen 5 is coming to servers and delivers stunning performance and power efficiency. The new top-end AMD EPYC Turin processor performance can obliterate the competition in most workloads and delivers a great generational leap in performance and power efficiency. Here are our first 5th Gen AMD EPYC Turin benchmarks in looking at the EPYC 9575F, EPYC 9755, and EPYC 9965 processors across many workloads and testing in both single and dual socket configurations.
Complementing the AMD EPYC 9575F / 9755 / 9965 performance benchmarks article looking at those Turin processors up against prior AMD EPYC CPUs and the Intel Xeon competition, this article is looking squarely at the 192-core EPYC 9965 "Turin Dense" processor compared to Ampere Computing's AmpereOne A192-32X flagship processor. It's an x86_64 vs. AArch64 battle at the leading 192 core count for performance and CPU power efficiency.
AMD is using their Advancing AI event today to announce 5th Gen EPYC "Turin" processors. With up to 192 cores / 384 threads per socket, 17% IPC uplift, AVX-512 with a full 512-bit data path, and the Zen 5 architectural improvements, these new EPYC 9005 processors deliver a significant generational improvement over the EPYC 9004 Genoa and Bergamo processors.
In addition to announcing the EPYC 9005 "Turin" processors and the latest on the AMD Instinct front, Lisa Su at the AMD Advancing AI event in San Francisco also announced the AMD Pensando Salina 400 DPU and AMD Pensando Pollara 400 Ultra Ethernet AI NIC.

It looks like for Linux 6.13 this Arm GCS support will be ready for upstreaming.
With the Xeon 6980P Granite Rapids benchmarking at Phoronix the past few weeks it's been in a dual socket (2S / 2P) configuration. For those curious about the Intel Xeon 6980P 128-core server performance for a single socket (1S) configuration, here are those complementary results out today and for both DDR5-6400 and MRDIMM-8800 memory configurations. Thus a well-rounded look at the single Xeon 6980P performance compared to other single and dual socket Intel Xeon and AMD EPYC server processors.
Intel's oneAPI Rendering Toolkit with the likes of OSPRay, Embree, OpenVKL, Open Image Denoise, and others has been open-source for years. But it's not been exactly an open-source development model with making it easy for independent contributors to propose code changes. But Intel has now decided to make these projects more like traditional open-source projects and welcoming community contributions -- including from different hardware vendors.
