Template:mpu Ryzen Threadripper 1950X is a 64-bit hexadeca-core high-performance x86 desktop microprocessor set to be introduced by AMD in mid-2017. The 1950X, which is based on their Zen microarchitecture, is fabricated on a 14 nm process. The 1950X operates at a base frequency of 3.4 GHz with a with a TDP of 180 W and a Boost frequency of 4.0 GHz. This MPU supports up to 128 GiB 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.

Memory controller

This CPU supports 8 DIMMs of rates 1,333 MT/s - 3,200 MT/s (UDIMM/SODIMM). Note that despite AMD's support for memory rates of 3,200 MT/s and possibly higher, rates beyond 2666 MT/s exceeds the JEDEC specification and is thus considered overclocking which voids AMD product warranty and likely any vendor or retailer warranties as well.
