I wish I never bought my 2019 MBP 16" 14nm and just stuck with my 2011 MBP 13" 32nm until the 2021 MBP 16" 5nm came out.I have an M2 Ultra Studio with 128Gb and 2Tb SSD arriving this week. But I’m going from a late 2019 16” MBP to the Studio so the performance bump should be insane.
I knew about the performance per watt gap of the iPhone vs same year Intel MBP as early as 2017.
Conventional thinking wouldn't allow me to think out of the box that Apple would leverage their iPhone chip fab capacity to jump from 14nm Intel to 5nm Mac chips resulting in higher raw performance, higher performance per watt, lower power consumption and longer battery life.
