Lenovo ThinkSystem AMD EPYC 7663 56C 225W 2GHz Processor w/o Fan for SR665

Fifty-six cores is an unusual count, and the AMD EPYC 7663 pairs it with a 2 GHz base clock and a 225 W TDP. Lenovo lists it as 4XG7A63606, without a fan, feature code BF75, for the ThinkSystem SR665.

The processor leans toward throughput. With a large pool of cores and a modest clock, it fits dense virtualization, container platforms and parallel jobs that fill every thread. It is not the right pick for software that waits on a single fast core.
