Ryzen Threadripper PRO 5965WX is a 64-bit 24-core high performance x86 workstation microprocessor introduced by AMD in March 2022. This multi-chip processor, which is based on the Zen 3 microarchitecture, incorporates four Core Complex Dies fabricated on a TSMC 7 nm process and an I/O die manufactured by GlobalFoundries. The PRO 5965WX has a TDP of 280 W with a base frequency of 3.8 GHz and a boost frequency of up to 4.5 GHz. This processor supports up to 2 TiB of octa-channel DDR4-3200 memory.

Cache

Main article: Zen 3 § 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.
