I tested the 2 versions on my GTX 1650 Super under the same conditions with go movetime 60000; NN 10x128

LC0 Cuda 0.26.3 backend cuda nps 19247
LC0 Cuda 0.26.3 backend cuda-fp16 nps 6634

LC0 CUDNN 0.26.3 backend cudnn nps 22990
LC0 CUDNN 0.26.3 backend cudnn-fp16 nps 37701

LC0 CUDNN 0.26.3 backend cuda nps 23732
LC0 CUDNN 0.26.3 backend cuda-fp16 nps 37573

So I think, the older cudnn version maybe the strongest with this card.
What do you mean by "the older cudnn version"?

Sorry ,
the cuda drivers are older only, the lc0 version is the same:
cublasLt64_11.dll 214.235.648 16.09.2020 05:17 -a-- in the CUDA package
or
cublas64_100.dll 67.318.784 26.08.2018 06:33 -a-- in the CUDNN package

clear now?

Classic loses to GTX card, but Lc0 likes to do something else :x . Are Lc0 developers cannot solve this issue?
