Pretty darn EPYC
"Alongside today’s EPYC 97x4 “Bergamo” announcement, AMD’s other big CPU announcement of the morning is that their large cache capacity “Genoa-X” EPYC processors are shipping now. First revealed by AMD back in June of last year, Genoa-X is AMD’s now obligatory V-cache equipped EPYC server CPU, augmenting the L3 cache capacity of AMD’s core complex dies by stacking a 64MB L3 V-cache die on top of each CCD. With this additional cache, a fully-equipped Genoa-X CPU can offer up to 1152MB of total L3 cache.
Genoa-X is the successor to AMD’s first-generation V-cache part, Milan-X. Like its predecessor, AMD is using cache die stacking to add further L3 cache to otherwise regular Genoa Zen 4 CCDs, giving AMD a novel way to produce a high-cache chip design without having to actually lay out an fab a complete separate die. In this case, with 12 CCDs on a Genoa/Genoa-X chip, this allows AMD to add 768MB of additional L3 cache to the chip."
