Ryzen Threadripper 1950 is a 64-bit hexadeca-core high-performance x86 desktop microprocessor set to be introduced by AMD in mid-2017. The 1950, which is based on their Zen microarchitecture, is fabricated on a 14 nm process. The 1950 operates at a base frequency of 3.2 GHz with a TDP of 155 W. This MPU supports up to 1 TiB of quad-channel DDR4-2666 ECC memory.

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.
