If numpy+mkl is faster, how much faster is it than numpy?

I found that the numpy+mkl installation package is much larger than numpy, but I can't feel the difference in their speed.

numpy's standard pip packages are linked to OpenBLAS. Mabey OpenBLAS is in the same ballpark for speed as MKL. For a detailed comparison of their speeds, please see Boosting numpy: Why BLAS Matters and Benchmark OpenBLAS, Intel MKL vs ATLAS
