AMD EPYC "Genoa" Zen 4 Fuite de la pile de produits

[ad_1]

With its recent announcement of the Ryzen 7000 processeurs de bureau, the action now shifts to the server, with AMD preparing a wide launch of its EPYC "Genoa" and "Bergamo" processors this year. Powered by the "Zen 4" microarchitecture, and contemporary I/O that includes PCI-Express Gen 5, Capcom ajoute des filtres d'écran à la version PC de Monster Hunter Rise, and DDR5, these processors dial the CPU core-counts per socket up to 96 in case of "Genoa," and up to 128 in case of "Bergamo." The EPYC "Genoa" series represents the main trunk of the company’s server processor lineup, with various internal configurations targeting specific use-cases.

Le 96 cores are spread twelve 5 nm 8-core CCDs, each with a high-bandwidth Infinity Fabric path to the sIOD (dé d'E/S du serveur), which is very likely built on the 6 nœud nm. Lower core-count models can be built either by lowering the CCD count (ensuring more cores/CCD), or by reducing the number of cores/CCD and keeping the CCD-count constant, to yield more bandwidth/core. The leaked product-stack table below shows several of these sub-classes of "Genoa" and "Bergamo," classified by use-cases. The leaked slide also details the nomenclature AMD is using with its new processors. The leaked roadmap also mentions the upcoming "Genoa-X" processor for HPC and cloud-compute uses, which features the 3D Vertical Cache technology.
