Another big unveil made by AMD during its recent live event is its highly anticipated EPYC Milan-X server CPU lineup which consists of four processors namely the EPYC 7773X features 64 cores and 128 threads, the EPYC 7573X features 32 cores and 128 threads, the EPYC 7473X features 24 cores and 48 threads while the EPYC 7373X features 16 cores and 32 threads.

The models along with their OPN codes are:

  • EPYC 7773X 64 Core (100-000000504)
  • EPYC 7573X 32 Core (100-000000506)
  • EPYC 7473X 24 Core (100-000000507)
  • EPYC 7373X 16 Core (100-000000508)

Firstly the flagship AMD EPYC 7773X rocks 64 cores, 128 threads, and features a maximum TDP of 280W and the clock speeds of the flagship are maintained at 2.2 GHz base and 3.5 GHz boost while the cache amount will drive up to an insane 768 MB.
