x86_64: Intel’s endless tock tock tock

Tick-Tock is a model used by Intel to follow every change to the micro-architecture[1] with a die shrink of the process technology. Every tick represents a shrinking of the process technology of the previous micro-architecture and every tock designated a new micro architecture.

According Seeking Alpha, Intel is stuck on tock and won’t move to 10 nanometers. Its Coffee Lake product is still going to be produced at 14 nanometers when it ships in 2018.

As the new IBM POWER9 will be a 14 nanometer chip, looks like it will take a while to see smaller processors in the market.
