Template:mpu Ryzen Threadripper 1920X is a 64-bit dodeca-core high-performance x86 desktop microprocessor set to be introduced by AMD in mid-2017. The 1920X, which is based on their Zen microarchitecture, is fabricated on a 14 nm process. The 1920X operates at a base frequency of 3.5 GHz with a TDP of 180 W and a Boost frequency of 4 GHz. This MPU supports up to 128 GiB of quad-channel DDR4-2666 ECC memory.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

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.

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.
