Intel’s Sapphire Rapids CPUs are going to launch in the last quarter of 2021, according to a leaked slide. Sapphire Rapids will succeed the Ice Lake-SP and leverage the Willow Cove architecture and the third iteration of the 10nm+++ node. They are rumored to be Intel’s first processor family to make use of DDR5 memory and the PCIe 5 standard.

Sapphire Rapids will use the new LGA4677 socket which will support 8-channel DDR5 memory and as many as 80 PCIe 5.0 lanes, plus Intel’s new CXL interface. Surprisingly, the LGA4677-based motherboards are expected to retain support for the 7nm Granite Rapids processors. (Diazepam) You might also like the following post:
