Several factors attributed to that jump in performance.

How in the world do you expect gains like that for every generation?
Subsequent designs were simply shrinks and tweaks of the original design. Shrinking stopped at 14nm as Intel had stubbed their toe on 10nm so Intel kinda had to make tweaks to Skylake and basically re-release the same CPUs every year on a more refined 14nm until 10nm works or 7nm is done. So pretty much no gains from Skylake onwards.
