VEAI use of GPU is not ‘linear’ with CU count/TFLOPS performance. I see the 3090 is getting better times than 3070 even if it’s not comparable with CU count/TFLOPS and it seems about the same as other user that tested 1.8.0 with both 3070 and 3090.
I must say, as I’ve stated to the other user, that the result of using a software passes between various possible ‘bottlenecks’, and each one can have an impact on the results.
