Sapphire Rapids
Sapphire Rapids is the Intel CPU microarchitecture based on the 3rd refinement of the 10 nanometer process (named 10nm Enhanced SuperFin).[1][2] It will be used as part of the Eagle Stream server platform in 2021.[3]

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.[4]
Sapphire Rapids will be used in CPUs powering one of the first exascale supercomputer in the United States, Aurora, at Argonne National Laboratory.[5]
Intel had confirmed that Sapphire Rapids would feature on-package HBM Memory support.[6]
