8 Hours Ago - Memory - Add A Comment

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.

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.

AMD EPYC 9755 / 9575F / 9965 Benchmarks Show Dominating Performance
10 October 02:00 PM EDT - Processors - 54 Comments

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.
