[N] IBM claims its machine learning library is 46x faster than TensorFlow. • r/MachineLearning

I don't use TF for its speed, I use it because it's practical. I can use the excellent Keras API to painlessly build my applications, and I know I can run them on my CPU, my GPU or the cloud with very minor changes. For a competitor to be better, being faster isn't enough, it has to be equally good in all the other important ways as well.
