How much faster is pytorch's GPU than CPU?

How much faster is pytorch’s GPU than CPU?

Depends on the network, the batch size and the GPU you are using.
This link gives some measures on torch models (which should be somewhat similar in run-time compared to PyTorch).
As an illustration, in that use-case, VGG16 is 66x slower on a Dual Xeon E5-2630 v3 CPU compared to a Titan X GPU.


Thank you very much, I see
