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.

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.

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.

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.
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...
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.
