EPYC 7371 is a dual-socket 64-bit 16-core x86 enterprise server microprocessor introduced by AMD in late 2018. This processor is based on the Zen 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.


Cache[edit]

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
