Comet Lake is the code-name for a possibly imminent series of upcoming Intel CPUs. Accord to some leaks, they will then be followed by Rocket Lake. A leaker claims to have uncovered a reference to a new ATX motherboard that may pertain to some of these chipsets.

The very last 14nm CPU! Rocket Lake-H comes out in Q1-Q2 2021, then after that, H-series CPUs for laptops will jump straight to 7nm with Meteor Lake-H! Fingers crossed!
