The 4090 had 50%+ shaders and clock speed over the 3090 though, the 5090 has +30% shaders but -4% clocks so don't expect anywhere near the uplift this time round.People said last Gen 4090 rasterisation must be hiding something because of the slides nvidia chose to show. It all worked out in the end and the uplift was very good. I wouldn't worry... at least on the top end.
