Succession

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[edit]

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[edit]

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

Architecture[edit]
