Ampere specs: https://www.nvidia.com/en-us/geforce/graphics-cards/compare/
This looks like a smaller bump than Ampere. 3090 seems cheaper and better than 4080. As people have pointed out, what I'd really like is more / upgradeable RAM. NVidia is trying to not compete with their higher-end cards, but ML tools are increasingly consumer.
It kinda feels like cheating.
This is starting to look like a repeat of Geforce FX vs Radeon 9700 Pro all over again.
