'''Xeon Platinum 8170F''' is a {{arch|64}} [[26-core]] [[x86]] multi-socket highest performance server microprocessor set introduced by [[Intel]] in late-2017. This chip supports up to 8-way multiprocessing. The Platinum 8170F, 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 2.1 GHz with a TDP of 165 W and a {{intel|turbo boost}} frequency of up to 2.8 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.

This specific model incorporates the {{intel|Omni-Path}} Host Fabric Interface (HFI) die in the same package as the processor.

The 165 W of TDP for this microprocessor consists of 157 W for the CPU and 8 W for the fabric.
