'''Xeon Silver 4112''' is a {{arch|64}} [[quad-core]] [[x86]] dual-socket mid-range performance server microprocessor introduced by [[Intel]] in mid-2017. The Silver 4112, which is based on the server configuration of the {{intel|Skylake (server)|Skylake|l=arch}} microarchitecture and is manufactured on a [[14 nm process]], sports 1 {{x86|AVX-512}} [[FMA]] unit as well as two {{intel|Ultra Path Interconnect}} links. This microprocessor, which operates at 2.6 GHz with a TDP of 85 W and a {{intel|turbo boost}} frequency of up to 3 GHz, supports up 768 GiB of hexa-channel DDR4-2400 ECC memory.

== Cache ==
{{main|intel/microarchitectures/skylake_(server)#Memory_Hierarchy|l1=Skylake § Cache}}
The Xeon Silver 4112 features a considerably larger non-default 8.25 MiB of [[L3]], a size that would normally be found on a 6-core part.
