Sapphire Rapids (SPR) is Intel's successor to Ice Lake, a 7 nm microarchitecture for enthusiasts and servers.
Contents
History[edit]
Sapphire Rapids was first announced during the May 2019 Intel Investor Meeting. Sapphire Rapids was planned to succeed Ice Lake in 2021, was however delayed to 2023.
Process Technology[edit]
Sapphire Rapids is planned to be manufactured on the Intel 7 process (previously 10nm Enhanced SuperFin (ESF)).
Compiler support[edit]
Support for Sapphire Rapids was added in LLVM Clang 12 and GCC 11.
