The AMD EPYC 7643 is a third-generation EPYC server processor with 48 Zen 3 cores and 96 threads, running at 2.3 GHz base and up to 3.6 GHz boost within a 225W TDP. It fits the SP3 socket and supports one- or two-socket servers with eight DDR4-3200 channels and 128 PCIe 4.0 lanes per socket. It suits virtualization hosts, database servers and dense compute nodes that need many cores and lots of memory bandwidth. Against Intel's 48-core Xeon Gold 6348 it offers more cache (256MB L3) and more PCIe lanes, but its 225W draw and the need for SP3 cooling and accessories make it a platform decision, not a drop-in upgrade.
