'''Sapphire Rapids''' ('''SPR''') is [[Intel]]'s successor to {{\\|Ice Lake (server)|Ice Lake}}, a [[7 nm]] [[microarchitecture]] for enthusiasts and servers.

== History ==
[[File:intel 2019 investor meeting sapphire roadmap.png|thumb|right|Intel Xeon Roadmap through 2021.]]
Sapphire Rapids was first announced during the May 2019 Intel Investor Meeting. Sapphire Rapids is planned to succeed {{\\|Ice Lake (Server)|Ice Lake}} in 2021.

== Process Technology ==
Sapphire Rapids is planned to be manufactured on the Intel 7 process (previously 10nm Enhanced SuperFin (ESF)).

== Compiler support ==
Support for Sapphire Rapids was added in LLVM Clang 12 and GCC 11.
