'''Xeon Platinum 8158''' is a {{arch|64}} [[dodeca-core]] [[x86]] multi-socket highest performance server microprocessor introduced by [[Intel]] in mid-2017. This chip supports up to 8-way multiprocessing. The Platinum 8158, 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 GHz with a TDP of 150 W and a {{intel|turbo boost}} frequency of up to 3.7 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.

== Cache ==
{{main|intel/microarchitectures/skylake_(server)#Memory_Hierarchy|l1=Skylake § Cache}}
The Xeon Platinum 8158 features a considerably larger non-default 24.75 MiB of [[L3]], a size that would normally be found on an 18-core part.
