The first wave of EPYC 7000 CPUs were able to reach only 3.2 GHz on boost clocks, but with the new EPYC 7371, AMD pushes the envelope up to 3.8 GHz, which is quite high for server-grade processors that don't usually benefit from custom air coolers or water coolers. The EPYC 7371 is aimed at design automation and high-frequency trading tasks, supporting dual-socket setups for improved performance.
