Hi. I tested 3d convolution models with 3070, nvidia’s official containers, pytorch 1.7.1, 1.8 nightly release, cudnn 8.0.4 and 8.0.5 and all combinations show the same speed.
Also I’m expecting similar to better performance than 2080 Ti in FP16 inference  (don’t know if I’m right though !), and I’m instead observing about 75% the perf right now.
I knnow this isn’t a benchmark post, but just to say : this soft will only technically support rtx 3000 in the “short” term.
