AMD's 3rd Gen 64 core EPYC "Milan-X" packs an insane 804MB of cache thanks to 3D V-Cache


AMD has launched today its new Milan-X EPYC CPUs that feature the company's 3D V-Cache technology. With the help of the new V-Cache or vertically stacked cache, AMD is able to cram in lots of cache memory into a smaller footprint. As such, the flagship Milan-X EPYC 7773X 64 core processor has an incredible 768MB of L3 cache. Couple that with the 32MB of L2 and 4MB of L1, and you get a total of 804MB of total cache on the new 64 core Milan-X EPYC CPU.

In total there are four SKUs that pack the new 3D V-cache. The full lineup alongside key specs and prices are given below (click on image to enlarge):

AMD first introduced the world to 3D V-Cache back at Computex 2021 and recently the firm shared the release date of the Ryzen 7 5800X3D desktop CPU that's launching soon. The 5800X3D however only has a fraction of the total L3 cache compared to the amount available at the disposal of the new EPYC 7003X CPUs announced today. That's because even the 16 core EPYC chips here comprise the full eight Core Complex Dies (CCDs) instead of the single CCD on the 5800X3D. This also shows the excellent nature of scalability of the 3D V-Cache.
