Last year Intel delayed its 10nm Cannonlake to the second half of 2017 and confirmed the 14nm process will have a cadence closer to 2.5 years instead of the usual 2-year cadence. As a result of this, Intel put a third 14nm chip on its roadmap, the upcoming Kaby Lake.
At the time, Intel promised it's doing its best to return to a 2-year cycle but according to the rumor mill Intel's 10nm roll out may once again follow a Tick-Tock-Tock model.
As always, it's best to take these rumors with a grain of salt but the fact that the rumor originated at Asian tech site BenchLife.info, which scored an exclusive in 2015 by leaking news about Intel's Kaby Lake, lends it some credence.
So there you have it, it looks like for the second time in a row, Intel may be forced to launch three CPU generations instead of its usual two on a single process node.
Intel's 14nm Kaby Lake is expected to be introduced in the second half of 2016 and the first 10nm processor, codenamed Cannonlake, is projected to arrive in the second half of 2017.
Cannonlake is anticipated to be succeeded by Icelake in the second half of 2018 and if this new rumor pans out there may be a third 10nm chip called Tigerlake in the second half of 2019. This implies the first 7nm chip from Intel isn't expected until at least the second half of 2020.
