'''Xeon Gold 5122''' is a {{arch|64}} [[quad-core]] [[x86]] multi-socket high performance server microprocessor introduced by [[Intel]] in mid-2017. This chip supports up to 4-way multiprocessing. The Gold 5122, 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]] unit as well as three {{intel|Ultra Path Interconnect}} links. This microprocessor, which operates at 3.6 GHz with a TDP of 105 W and a {{intel|turbo boost}} frequency of up to 3.7 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.
+
'''Xeon Gold 5122''' is a {{arch|64}} [[x86]] high-performance server [[dodeca-core]] [[multiprocessor]] set to be introduced by [[Intel]] in the second quarter of 2017. This processor is based on the server configuration of the {{intel|Skylake|l=arch}} microarchitecture (a {{intel|Skylake SP|l=core}} core) and is manufactured on Intel's [[14 nm process]]. The 5122 operates at 3.6 GHz.
