When it comes to matrices the difference can be quite big. You can find the comparison of NumPy, Fortran 77, C, and C++ for matrix multiplication with and without optimized BLAS at http://matrixprogramming.com/MatrixMultiply/ NumPy interfaces optimized BLAS, and you can find a LAPACK interface in SciPy, so it is a good choice.
