alt Hacker NewsOne thing I am not entirely sure if there will be huge efficiency gains. Just looking at TDP that is the power consumption of say 3090 and 5090 and the increase is substantial then compare it to performance and the performance lift stops looking that great...
3x increase in compute for a 1.5x increase in tdp is pretty good considering the underlying process had barely changed. In anycase, consumer GPUs aren't a good metric as they operate with different economic constraints.
H100 to GB200 saw a 50x increase in efficiency, for example.
