Process Technology

See also: Cannon Lake § Process Technology

Ice Lake will use a second-generation enhanced 10 nm process called "10 nm+". Versus the first generation 10nm which was used for Cannon Lake, 10nm+ will feature higher performance through higher drive current for the same power envelope.

Compiler support

Support for Ice Lake was added in LLVM Clang 6.0 and GCC 8.0.
