pas mal
il y a de l'amélioration surtout en terme de perf/watts
mais le 128 cœurs AMD reste devant

the AMD EPYC 9754 is the flagship part with 128 cores and 256 threads at $11,900
The primary change for Zen 4c cores from Zen 4 is a halving of L3 cache.
The AMD EPYC 9754 is showing performance ~3x a 128-core Arm competitor at 1.5x the power.
An AMD EPYC 9754 is often twice the performance of 2019’s AMD EPYC 7002 “Rome” 64-core parts.
On most non-HPC-focused workloads, expect the AMD EPYC 9754 to be 15-20% faster than the AMD EPYC 9654. That is not a straight 33% as we would expect due to the core count increase, but AMD is getting scaling from the increased core count even with a drastically reduced L3 cache size.
AMD seems to have figured out an elegant way to reduce turbo clock jitter, especially at maximum load. That helps a lot with SLA on a loaded system.
Cloud-native processors will make up a huge segment of the market.

"The 64-core EPYC 9554 2P was 64% faster than the 64-core EPYC 7763 2P configuration overall,
or 67% if running the EPYC 9554 2Ps in the power determinism mode.
(...)The AMD EPYC 9654 2P was running at over 2x the speed of Intel's current flagship, the Xeon Scalable 8380 2P "Ice Lake" processors.
"the generational gains from Milan(X) to Genoa were some of the most captivating generational improvements and against the competition that I've seen out of the past 18+ years of running Phoronix for Linux hardware reviews"

N'allez pas non plus crier sur les toits que le TDP de base pourra monter à 225W (et jusqu'à 240W max). Je compte sur vous.
Binary code was not a verified news or even a rumor. Just what I saw on a very early sample. Still have the CPUZ dump
