'''Xeon Gold 6146''' is a {{arch|64}} [[dodeca-core]] [[x86]] multi-socket high performance server microprocessor introduced by [[Intel]] in mid-2017. This chip supports up to 4-way multiprocessing. The Gold 6146, which is based on the server configuration of the {{intel|Skylake (server)|Skylake|l=arch}} microarchitecture and is manufactured on a [[14 nm process|14 nm+ process]], sports 2 {{x86|AVX-512}} [[FMA]] units as well as three {{intel|Ultra Path Interconnect}} links. This microprocessor, which operates at 3.2 GHz with a TDP of 165 W and a {{intel|turbo boost}} frequency of up to 4.2 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.
