'''W-2123''' is a {{arch|64}} [[quad-core]] [[x86]] enterprise performance workstation microprocessor introduced by [[Intel]] in [[2017]]. This processors, which is fabricated on an enhanced [[14 nm process|14nm+ process]] based on the {{intel|Skylake (server)|Skylake}} server microarchitecture, operates at 3.6 GHz with a [[TDP]] of 120 W and a {{intel|turbo boost}} frequency of up to 3.9 GHz. This chip supports up to 512 GiB of quad-channel DDR4-2666 ECC memory.
