Granite Rapids is a codename for Intel's sixth generation Xeon server and workstation processors based on Intel 3, a refined version of their Intel 4 node.[2][3] Granite Rapids CPUs are all P-core CPUs designed for single thread performance compared to their platform equivalent Sierra Forest all E-core CPUs, of which they share a socket and platform; the contemporary Meteor Lake is intended for consumer use.[4][5]
At Intel DCAI 2023, Granite Rapids was announced to be targeting a H1 2024, and an early engineering sample chip was shown running 8800 MT/s DDR5.[6]
