[hide]History[edit]
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
(7 nm) process (previously 10nm Enhanced SuperFin (ESF)).
Models[edit]
Sapphire Rapids-based Xeon Processors[edit]
- Introduced in 2023, the 4th generation Xeon Scalable processors (Sapphire Rapids-SP and Sapphire Rapids-HBM) and
Xeon W-2400 and W-3400 series (Sapphire Rapids-WS) provide large performance enhancements over the prior generation.
