Revision as of 06:19, 3 August 2017

Cannonlake (CNL) (formerly Skymont) is a planned microarchitecture by Intel as a successor to Kaby Lake. Cannonlake is expected to be fabricated using a 10 nm process and is set to be introduced in the fourth quarter of 2017. Cannonlake is the "Process" microarchitecture as part of Intel's PAO model.

For mobile, Cannonlake is expected to be branded as 8th Generation Intel Core i3, Core i5. and Core i7 processors. There will be no desktop Cannonlake models.

Process Technology

Cannonlake is manufactured on Intel's 10 nm process (P1274). Intel's 10 nm process is the first high-volume manufacturing process 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	Cannonlake	Δ
	14 nm	10 nm
Fin Pitch	42 nm	34	0.81x
Fin Width​	8 nm	? nm	?x
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

Codenames

Intel cancelled Desktop Cannonlake models.
