'''EPYC 7371''' is a dual-socket {{arch|64}} [[16-core]] [[x86]] enterprise server microprocessor introduced by [[AMD]] in late [[2018]]. This processor is based on the {{amd|Zen|l=arch}} microarchitecture and is manufactured on a [[14 nm process]]. The 7371 has a base frequency of 3.1 GHz with a turbo frequency of up to 3.8 GHz. This chip has a TDP of 200 W and supports up to 2 TiB of octa-channel DDR4-2666 ECC memory per socket.
