Ryzen Threadripper 2920X is a 64-bit dodeca-core high-performance x86 desktop microprocessor introduced by AMD in mid-2018. The 2920X, which is based on their Zen+ microarchitecture, is fabricated on a 12 nm process. The 2920X operates at a base frequency of 3.4 GHz with a TDP of 180 W and a boost of up to 4.3 GHz. This MPU supports up to 1 TiB of quad-channel DDR4-2933 memory.

Cache

Main article: Zen+ § 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.
