4080 is faster by about 15% than 3090Ti. People hated it cuz it was priced pretty high, not because it's perfomance. I mean, non Ti-version of high-end card beats down the Ti version of previous gen 'top tier'.
I'm pretty sure even 4070Ti is faster than 3090Ti - no much, probably within a margin about 5-10%.
And it's just considering a 'raw power', no rtx\dlss technlogy\hardware updates.
7900XTX is almost equal to 4080. But no fancy Nvidia stuff, rtx performance is closer to 30xx cards than current Nvidia gen.
As for VaM, there was someone who tested it vs 4080 [with 13900k cpu if i recall] and 4080 was performing better.
