'''W-3175X''' is a {{arch|64}} [[28-core]] [[x86]] enterprise performance workstation microprocessor introduced by [[Intel]] in early [[2019]]. This processor is fabricated on an enhanced [[14 nm process|14nm++ process]] based on the {{intel|Skylake (server)|Skylake}} server microarchitecture, operates at 3.1 GHz with a [[TDP]] of 255 W and a {{intel|turbo boost}} frequency of up to 4.3 GHz. This chip supports up to 512 GiB of hexa-channel DDR4-2666 ECC memory.

The Xeon W-3175X is the only Xeon with a multiplier unlocked for [[overclocking]].
