AMD is going to release EPYC Genoa-X 3D V-Cache processors by the end of this year. Along with Zen 4 cores, these processors are also equipped with huge cache blocks. according to New information that has been published, now we know the exact amount of additional cache of these processors and can comment more precisely about the second generation of EPYC 3D V-Cache processors. Now we know the exact amount of additional cache of these processors and we can comment more precisely about the second generation of EPYC 3D V-Cache processors.
AMD EPYC Genoa-X processors
According to the table below, the information of two AMD EPYC Genoa-X processors has been released; One of them is an engineering sample with the code 000000892-04-100 and the other is a final sample with the code 000000892-06-100. Both processors are from the B1 development phase and are based on the SP5 socket. The configuration of the cores of these processors is the same as the regular Genoa models and is 12 CCD units based on the Zen 4 architecture, except that each CCD is equipped with a 3D V-Cache block with an additional 64 MB of L3 cache.
With this AMD EPYC Genoa-X processors will have a total of 384 MB of L3 cache on CCDs, 768 MB of L3 cache on 3D V-Cache blocks and 96 MB of L2 cache, for a total of 1248 MB. There is also a 3MB L1 cache for these processors, which is used for basic instructions. With this account, we see 2.6 times the cache of these processors compared to standard Genoa and a 56% increase in cache compared to Milan-X processors (the first generation of EPYC 3D V-Cache processors). All processors in this series consume 400 watts, and their base thermal power is set to 320 watts.
Regarding the frequency, it seems that AMD plans to limit the maximum frequency of these processors to 3.7 GHz, which is the same as the maximum frequency of the 96-core EPYC 9654 processor. The maximum temperature tolerated by these processors is also 100 degrees Celsius.
With this account, the 96-core EPYC 9684X processor with 1152 MB of L3 cache will be the flagship of this series. The 32-core EPYC 9384X processor, the 24-core EPYC 9284X processor and the 16-core EPYC 9184X processor will also be available from this series. All of these processors are specifically optimized for cache-intensive processing, just like the previous generation of EPYC 3D V-Cache processors. These processors will be released in the middle of 2023.
