While the original tweet has been deleted, the performance of the 4090 so far is in line with what kopite said a year ago:
NVIDIA Ada Lovelace ‘GeForce RTX’ & AMD RDNA 3 ‘Radeon RX’ Next-Generation GPUs Rumored To Be More Than Twice As Fast Than Ampere & RDNA 2
https://wccftech.com/nvidia-ada-lovelace-geforce-rtx-amd-rdna-3-radeon-rx-next-generation-gpus-rumored-twice-as-fast-than-ampere-rdna-2/
based on drafts, by my calculation only, the perf scale I guess:
NAVI21 0.9X
GA102 1X
AD102 2.2X
NAVI31(4 GCDs) >2.5X
GH202 >3X
I'm optimistic. But Jensen and Lisa need time to solve problems especially bandwidth. Boring days, wait and see.
