and on top of all of that, transistor density no longer works are a rough approximation of performance either. clock rate may get worse, with a more dense node, heat issues may not let them actually put more transistors in the same area despite the smaller pieces, etc etc etc.

as usual, the only way to actually judge a cpu's tech is how many frames of doom it can render per second ;)

if any pedant responds to this about how modern doom is mostly a function of GPU I will kill a kitten.
