I got an old, but cheap nvidia gpu (k40) to play with deep learning while i'm searching for a reasonably priced modern card.

To my surprise, the i7-1165G7 CPU (8 cores) is about twice faster than the GPU doing classification of images with a CNN.

Is it something one would expect. Did CPU's get better recently? Is the GPU I got too slow?


to be fair, ai-benchmark assigned the score of 5330 to the GPU and 1397 to the CPU.
