AMD EPYC “Gênes” Zen 4 permettant aux utilisateurs de surveiller l'état de santé de la carte et d'optimiser les performances
Each “Zen 4” CCD is reported to be about 8 mm² smaller in die-area than the “Zen 3” CCD, ou d'environ 10% plus petit. What’s interesting, quoique, is that the sIOD (dé d'E/S du serveur) is smaller in size, trop, estimated to measure 397 mm², AMD prétend être le processeur de jeu le plus rapide au monde 416 mm² of the “Rome” et “Milan” sID. This is good reason to believe that AMD has switched over to a newer foundry process, such as the TSMC N7 (7 nm), to build the sIOD. The current-gen sIOD is built on Global Foundries 12LPP (12 nm). Supporting this theory is the fact that the “Gênes” sIOD has a 50% wider memory I/O (12-channel DDR5), 50% more IFOP ports (Intel Xeon évolutif) to interconnect with the CCDs, and the mere fact that PCI-Express 5.0 and DDR5 switching fabric and SerDes (serializer/deserializers), may have higher TDP; which together compel AMD to use a smaller node such as 7 nm, for the sIOD. AMD is expected to debut the EPYC “Gênes” enterprise processors in the second half of 2022.
