les informations qui circulent évoquent un nouveau design de puce CCD (Core Complex Die) pouvant intégrer jusqu’à 16 cœurs,
ainsi que jusqu’à 224 Mo de cache L3
sur un seul chiplet équipé de la technologie 3D V-Cache.
the AMD EPYC 9745 was delivering about 90% the performance of its 128 core EPYC 9755 sibling. Considering that the EPYC 9745 has just 80% the TDP rating of the EPYC 9755, that's a nice showing for the EPYC 9745 with its dense cores. When pulling back to the 320 Watt lowest cTDP, it was around 98% the performance of the 400 Watt default.
Across the mix of different workloads tested, the EPYC 9745 consumed 73% the power of the EPYC 9755 across the mix of workloads tested. The peak CPU power was at 379 Watts for the EPYC 9745 compared to 497 Watts with the EPYC 9755. With the 320 Watt cTDP power configuration was the additional power savings.
And lastly the system DC power consumption as reported by the Corsair HX1500i power supply used for this Gigabyte server.
Overall the AMD EPYC 9745 offered good performance relative to the EPYC 9755 with its full Zen 5 cores and higher TDP while offering quite a nice lead in performance-per-Watt across the many workloads tested. The EPYC 9745 is a great choice for those concerned about maximizing the power efficiency of your EPYC 9005 series server build and/or limited to a maximum 400 Watt TDP rated processors by your server platform.
Intéressant, le Zen 5c reste pas mal
au boulot on a un hyperviseur Proxmox avec un Epyc 128 cœurs Zen 4c
Les processeurs Epyc 9006 “Venice” avec Zen 6C pourront atteindre jusqu’à 256 cœurs et 512 threads, tandis que la version standard se limitera à 96 cœurs et 192 threads. Ces processeurs offriront une bande passante CPU-GPU doublée et une amélioration des performances de 70 % par rapport à la génération précédente.

arrivée fin juin
il faudra privilégier ce chipset et ces cartes mères
pas de ventilo mais du PCI-E 4.0
