EPYC 9354P is a 64-bit 32-core x86 server microprocessor designed and introduced by AMD in late 2022. This multi-chip processor, which is based on the Zen 4 microarchitecture, incorporates eight Core Complex Dies fabricated on a TSMC 5 nm process and a large I/O die also manufactured by TSMC. The 9354P has a TDP of 280 W with a base frequency of 3.25 GHz and a boost frequency of up to 3.8 GHz. This processor supports up to 6 TiB of 12 channel DDR5-4800 memory per socket.

Cache

Main article: Zen 4 § Cache

[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.
