'''Ryzen Threadripper 1900X''' is a {{arch|64}} [[octa-core]] high-performance [[x86]] desktop [[microprocessor]] set to be introduced by [[AMD]] in mid-[[2017]]. The 1900X, which is based on their {{amd|Zen|Zen microarchitecture|l=arch}}, is fabricated on a [[14 nm process]]. The 1900X operates at a base frequency of 3.8 GHz with a [[TDP]] of 180 W and a {{amd|Precision Boost|Boost}} frequency of 4 GHz. This MPU supports up to 1 TiB of quad-channel DDR4-2666 ECC memory.

As with the rest of the {{amd|Threadripper}} family based on {{amd|Zen|l=arch}}, the 1900X consists of two [[dies]] with one {{amd|Zen#CPU Complex (CCX)|CPU Complex (CCX)|l=arch}} disabled in each die. That is, [[four cores]] in a single CCX in each of the dies are active for a total of [[eight cores]] in the entire [[package]] (4+0 [Die 1] + 4+0 [Die 2]).
