AMD has three new SKUs as part of its newest high-cache chip lineup. What might surprise our readers is the core counts as AMD is going after two very different markets with the new AMD Genoa-X series. While many may expect a 96 cores 1.1GB of L3 cache behemoth, others may not be expecting a part with 48MB of L3 cache.
AMD EPYC Genoa-X SKU List
Still built around the same Zen 4 architecture that we saw with the original AMD EPYC Genoa, the new chips add 3D V-Cache. For folks wondering, this is very much in line with the AMD EPYC Milan-X.
The high-end 12x CCD version is the AMD EPYC 9684X at $14,756 list price. This 96-core chip has 1152MB of L3 cache which may even not be the craziest.
AMD also has two chips, seemingly made for per-core licensing (e.g. 16 cores for Windows Server and 32 cores for VMware.) The AMD EPYC 9384X is a 32-core part with 768MB of L3 cache at $5529. Perhaps the crazier one is the AMD EPYC 9184X which has the same 768MB of L3 cache for a total of 48MB of L3 cache per core. The $4928 list price of that part may seem like a lot, but if you are optimizing on per-core performance, that extra L3 cache can have a huge dollar impact.
AMD has a strategy where it now has three server CPU lines in the same socket. The mainstream Genoa, the high-core count, Bergamo, and the high-cache Genoa-X. As we have mentioned previously, the big win will be a future part combining reduced base-die cache / high core count chips with L3 cache stacked. We think it is at least a generation away, but Bergamo-Next-X is going to be a fascinating part.
As you would expect, we will have a full review with benchmarks when the embargo lifts.
