Golden Cove is the successor to Willow Cove, a high-performance 10 nm x86 core microarchitecture designed by Intel for an array of server and client products, including Sapphire Rapids (server) and Alder Lake (client).

History

Intel Core roadmap

Golden Cove was originally unveiled by Intel at their 2018 architecture day. Golden Cove is intended to succeed Willow Cove in the 2021 timeframe.

Process Technology

Intel has confirmed that the Golden Cove architecture will be fabricated on their Intel 7 process (previously 10 nm Enhanced SuperFin (ESF)).
