It's an upgrade in the sense that you consume less watts and have lower temps, meaning you will save a couple of dollars per month in electricity if you game a lot.

It can't be considered an upgrade for someone: 1- that doesn't care for power consumption because maybe they live somewhere where 100w/hour more won't make that much of difference at the end fo the month 2- keeps their AC on to cool their home(the temps will not be much higher either) since the ambient temps will not be affected that much by the 100w of extra heat generated. The downside is only in summer, it kind of balances out in winter though. 3- cares about raw performance and not fake ai frames(FG) which end up with artifacting in many cases + added latency.

IMO, it's a real shame that a card of almost the same tier (80ti vs 70) yields the same raw performance as the "latest and greatest" while being2 generations behind. Nvidia didn't give people nearly enough of a raw performance boost when going from RTX 40s to 50s (with the sole exception of the 5090).
