That's a false analogy. What I'm saying is not like "Numpy is faster than Python"; it's like "Numpy is faster than some scientific computing that the creators of a Python framework hand-rolled separately." Some frameworks write their own CUDA kernels for operations beyond what cuDNN offers, and also wrap cuDNN. So certain operations may run faster or slower depending on how you choose to execute them with the framework.
