EPYC Embedded 3401 is a 64-bit hexadeca-core x86 embedded microprocessor introduced by AMD in early 2018 for dense servers and edge devices. Fabricated on a 14 nm process based on the Zen microarchitecture, this chip operates at 1.85 GHz with a TDP of 85 W and a turbo frequency of up to 3 GHz. The 3401 supports up to 1 TiB of quad-channel DDR4-2666 ECC memory.

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.
