I have 2 computers, these are their configurations:

16 GB RAM, GeForce GTX 1070, i7-8700, Debian testing, Python 3.8.3;
32 GB RAM, GeForce GTX 1070, i7-7700K, Manjaro Linux 20.1, Python 3.8.

I run the same experiment in both machines, using PyTorch 1.6.0, CUDA 10.2 and NVIDIA drivers 440.100. In the first machine, one experiment takes 11 hours. In the second, it takes 48 hours.
I am unable to find what’s so significantly different between the two computers that cause such a large difference in execution time. Does anyone have any knowledge about what can cause this?
