'''Ryzen Threadripper PRO 3975WX''' is a {{arch|64}} [[32-core]] high performance [[x86]] workstation [[microprocessor]] introduced by [[AMD]] in mid-[[2020]]. This [[multi-chip package|multi-chip processor]], which is based on their {{amd|Zen 2|Zen 2 microarchitecture|l=arch}}, incorporates four Core Complex Dies fabricated on a [[TSMC]] [[7&nbsp;nm process]] and an I/O die fabricated on a [[GlobalFoundries]] [[12&nbsp;nm process]]. The PRO 3975WX has a {{abbr|TDP}} of 280&nbsp;W with a base frequency of 3.5&nbsp;GHz and a {{amd|precision boost|boost}} frequency of up to 4.2&nbsp;GHz. This processor supports up to 2&nbsp;TiB of octa-channel DDR4-3200 memory.
