'''Ryzen Threadripper 1920X''' is a {{arch|64}} [[dodeca-core]] high-performance [[x86]] desktop [[microprocessor]] introduced by [[AMD]] in mid-[[2017]]. The 1920X, which is based on their {{amd|Zen|Zen microarchitecture|l=arch}}, is fabricated on a [[14 nm process]]. This processor operates at a base frequency of 3.5 GHz with a [[TDP]] of 180 W and a {{amd|Precision Boost|boost}} frequency of up to 4 GHz. This MPU supports up to 1 TiB of quad-channel DDR4-2666 ECC memory.
