Sapphire Rapids is the Intel CPU microarchitecture based on either the second refinement of the 10 nanometer process[1] or a new 7 nanometer process.[2][3] It will be used as part of the Tinsley workstation and server platform after 2020.[2]

Only very limited information on the desktop/mobile version of Sapphire Rapids exists as of January 2018. Difficulties with the 10 nm and 7 nm fabrication processes may result in the release being pushed back to 2021 at the earliest.[4]

A leaked Intel slide shows DDR5 SDRAM support among the new features of Sapphire Rapids, where the integrated memory controller of previous microarchitectures used DDR4 SDRAM.[5]

Sapphire Rapids will be the processor for the first exascale supercomputer in the United States, Aurora, at Argonne National Laboratory.[6]
