Cannon Lake (CNL) (formerly Skymont) is a planned microarchitecture by Intel as a successor to Kaby Lake. Cannon Lake is expected to be fabricated using a 10 nm process and is set to be introduced in the second half of 2018. Cannon Lake is the "Process" microarchitecture as part of Intel's PAO model.

For mobile, Cannon Lake is expected to be branded as 8th Generation Intel Core i3, Core i5. and Core i7 processors.

Process Technology

Cannon Lake is manufactured on Intel's 10 nm process (P1274). Intel's 10 nm process is among the first high-volume manufacturing processes to employ Self-Aligned Quad Patterning (SAQP) (goes under the "Hyper-Scaling" marketing name). Intel's 10nm features a 0.0367 µm² SRAM bit cell.

Scaling:

	Broadwell	Cannon Lake	Δ
	14 nm	10 nm
Fin Pitch	42 nm	34	0.81x
Fin Width​	8 nm	7 nm	0.88x
Fin Height​	42 nm	53 nm	1.24x
Gate Pitch	70 nm	54 nm	0.77x
Interconnect Pitch	52 nm	36 nm	0.69x
Cell Height	399 nm	272 nm	0.68x

Compiler support

Support for Cannon Lake was added in GCC 8.1 and LLVM 6.0.
