Intel gives a tick-tock model to cpu advancements.
Tock is an advancement, tick is a refinement to smaller, tighter more efficient of the last advancement, but same technological level otherwise. Thus tock increases size/footprint, and tick shrinks that into a smaller size/footprint of cpu to same functionality.
.
Easy job is just time tick to refine, polish moves, while in a different mode/aspect view/gear to me.
Might try few new things cuz slack, but mostly necessity being such a mutha, births innovations in tock, that refine later.
