Cannon Lake (formerly Skymont) is Intel's codename for the 10-nanometer die shrink of the Kaby Lake microarchitecture. As a die shrink, Cannon Lake is a new process in Intel's "Process-Architecture-Optimization" execution plan as the next step in semiconductor fabrication. Cannon Lake CPUs are the first mainstream CPUs to include the AVX-512 instruction set.
Cannon Lake was initially expected to be released in 2015/2016, but the release was pushed back to 2018. Intel demonstrated a laptop with an unknown Cannon Lake CPU at CES 2017 and announced that Cannon Lake based products would be available in 2018 at the earliest.
On April 26, 2018 in its report on first-quarter 2018 financial results Intel stated it was currently shipping low-volume 10 nm product and expects 10 nm volume production to shift to 2019. In July 2018, Intel announced that volume production of Cannon Lake would be delayed yet again, to late Q2 2019.
The first laptop featuring a Cannon Lake CPU, namely Intel Core i3-8121U, a dual core CPU with Hyper-Threading and Turbo Boost but without an integrated GPU, was released in May 2018 in very limited quantities.
On October 28, 2019, Intel announced that it will be discontinuing the i3-8121U and the Cannon Lake-powered Crimson Canyon NUC, with orders being taken till December 27th, and shipping till February 28, 2020, making Cannon Lake not only one of the shortest-lived microarchitectures of Intel, but also the shortest-lived 10nm x86 CPU microarchitecture (with only one CPU model to be released and manufactured for 1.5 years).
Architecture changes compared to Coffee Lake
- AVX-512 instruction set extension
