'''Ryzen Threadripper 3990X''' is a {{arch|64}} [[64-core]] high-performance [[x86]] desktop [[microprocessor]] introduced by [[AMD]] on February 7, [[2020]]. The 3990X, which is based on their {{amd|Zen 2|Zen 2 microarchitecture|l=arch}}, is fabricated on [[TSMC]]'s [[7 nm process]]. The 3990X operates at a base frequency of 2.9 GHz with a [[TDP]] of 280 W and a {{amd|precision boost|boost}} of up to 4.3 GHz. This MPU supports up to 512 GiB of quad-channel DDR4-3200 memory.
