AMD EPYC 7642

48C/96T · 3.3 GHz · 225 W

The EPYC 7642 is a 48-core, 96-thread second-generation EPYC (Rome) processor launched on August 7, 2019 for one- and two-socket servers. It spreads its cores across all eight 7 nm compute dies with three active cores per core complex, which keeps the full 256 MB of L3 cache, and runs at 2.3 GHz base and 3.3 GHz boost within a 225 W TDP. It is the higher-clocked of the two 48-core models in the original Rome lineup, above the 200 W EPYC 7552.
