The cache performance of AMD's flagship Milan-X 3D V-Cache CPU, the EPYC 7V73X, has been tested against standard Milan & showcases phenomenal results.

The flagship AMD EPYC 7V73X CPU will rock 64 cores, 128 threads and feature a maximum TDP of 280W. The clock speeds will be maintained at 2.2 GHz base and 3.5 GHz boost while the cache amount will drive up to an insane 768 MB. This includes the standard 256 MB of L3 cache that the chip features so essentially, we are looking at 512 MB coming from the stacked L3 SRAM which means that each Zen 3 CCD will feature 64 MB of L3 cache. That's an insane 3x increase over the existing EPYC Milan CPUs.
