assez catastrophique ...
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.

à voir si c'est vraiment perceptible hum
un site potable pour estimer son crédit immo
RAM encore soudée ... (32 voir 64Go) à part le P16v
mais USB 4.0 donc Thunderbolt en théorie
4.3" la c'est compact ! :)
RX 6800 XT.
Sans surprise, on constate que le SSD Nvme, doté d'une interface PCi-e 3.0, est le plus efficient dans ce domaine, il effectue le chargement en seulement 0.70 seconde, contre 4.43 secondes pour le SSD SATA et 5.86 secondes pour le disque dur SATA
rassurant
Topachat
45€ les 32GO DDR4 SoDimm WTF !!
même le N2 en 4+1 est pas mal
