'''EPYC 7551P''' is a {{arch|64}} [[32-core]] [[x86]] enterprise server microprocessor introduced by [[AMD]] in mid-[[2017]]. This processor is based on the {{amd|Zen|l=arch}} microarchitecture and is manufactured on a [[14 nm process]]. The 7551P has a base frequency of 2 GHz with a turbo frequency of 3 GHz for up to 12 active cores. This chip has a TDP of 180 W and supports up to 2 TiB of octa-channel DDR4-2666 ECC memory.
