EPYC 7662 is a 64-bit 64-core x86 server microprocessor designed and introduced by AMD in February 2020. This multi-chip processor, which is based on the Zen 2 microarchitecture, incorporates 8 compute dies fabricated on a TSMC 7 nm process and an I/O die fabricated on a GlobalFoundries 14 nm process. The 7662 has a TDP of 225 W with a base frequency of 2 GHz and a boost frequency of up to 3.3 GHz. This processor supports up to two-way SMP and up to 4 TiB of eight channels DDR4-3200 memory per socket.

[Edit/Modify Cache Info]

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.
