AMD EPYC Genoa-X CPUs Outfitted With 3D V-Cache Carry 1.25 GB of Cache, 2.6x Higher Than Standard Genoa Chips
AMD's EPYC Genoa-X CPUs with 3D V-Cache are expected to launch this year with large pools of cache alongside the Zen 4 cores.
New information shows the exact amount of cache and clocks that we could expect from the upcoming server chips and the 2nd EPYC family with 3D V-Cache technology.According to a leaked spec sheet, we get to see details of two AMD EPYC Genoa-X CPUs which carry the same specs but one of them is an ES part "100-000000892-04" while the other is a retail sample "100-000000892-06".
Both chips feature support on the SP5 socket and come in a "B1" revision. It's going to be a similar core configuration as the existing Genoa chips with 12 Zen 4 CCDs and a single I/O die but each of the Zen 4 CCDs will feature a 3D V-cache stack with up to 64 MB of L3 cache.So for AMD's EPYC Genoa-X CPUs, that's 384 MB of L3 cache from the CCDs, 768 MB of L3 cache from the 3D V-Cache stacks, & 96 MB of L2 cache for a total of 1248 MB cache.
There are also 3 MB of L1 cache (Instruction/data). This is 2.6x higher cache than the standard Genoa chips and also a 56% increase in cache amount versus the Milan-X (1st Gen EPYC 3D V-Cache chips).
