>""Intel 4"" is inferior to Samsung's and TSMC's 5nm processes on paper {...}

According to transistor density information this is false (https://en.wikipedia.org/wiki/5_nm_process)

TSMC 5nm density: 173 MTr/mm^2

Samsung 5nm density: 127 MTr/mm^2

Intel 4 (estimated): ~200 MTr/mm^2

Got a source? I'm willing to change my mind, but the data doesn't agree with your assertion from my point of view.

Samsung's process has always lagged TSMC and INTC. It's part of why the 3080 is so hot/power hungry.
