EPYC 7502P is a 64-bit dotriaconta-core x86 server microprocessor designed and introduced by AMD in mid-2019. This multi-chip processor, which is based on the Zen 2 microarchitecture, incorporates logic fabricated TSMC 7 nm process and I/O fabricated on GlobalFoundries 14 nm process. The 7502P has a TDP of 180 W with a base frequency of 2.5 GHz and a boost frequency of up to 3.35 GHz. This processor supports single-socket configurations only and up to 4 TiB of eight channels DDR4-3200 memory per socket.

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.
