Intel has had no trouble moving their mainstream product lines from 2-4 cores up to 6-10 cores, without copying AMD's chiplet playbook, or using their own more ambitious chiplet interconnects, or even delivering significant improvements to their CPU fabrication process. They just stretched out a ring bus a bit further to add in more of the same CPU cores they'd been shipping for years, with very incremental improvements/fixes. Aside from some of the clock speed increases and some of the integrated GPU updates, all the big improvements they've made to their consumer 14nm chips since 2015's Skylake are things they could have delivered in 2016 if there had been competitive pressure.
