Tick - New cores; Tock - Scaling up the number of those same cores

I think most of the work went into the uncore portions of the SOC this time.

FYI it's the reverse. "Tock" is a new microarchitecture, and "tick" is a process shrink.

Also, scaling the number of cores up and down for different tasks happens in both. Apple's recent announcement doesn't fit the tick-tock model at all.

In this case, both are using the same CPU core designs and are on the same node.

However, they are following the notion of "don't change everything at once".

uncore?

Parts of the SoC that are not the main CPUs e.g. power management controllers, display controllers, etc.
