Sapphire Rapids (SPR) is Intel's successor to Ice Lake, a 7 nm microarchitecture for enthusiasts and servers.

History[edit]

Intel Xeon Roadmap through 2021.

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.

Compiler Arch-Specific Arch-Favorable
GCC -march=sapphirerapids -mtune=sapphirerapids
