Here's the same benchmark with numpy instead of native python (on M2 MBP)

    Python             4.216 GFLOPS
    Naive:             6.400 GFLOPS            1.52x faster than Python
    Vectorized:       22.232 GFLOPS            5.27x faster than Python
    Parallelized:     52.591 GFLOPS           12.47x faster than Python
    Tiled:            60.888 GFLOPS           14.44x faster than Python
    Unrolled:         62.514 GFLOPS           14.83x faster than Python
    Accumulated:     506.209 GFLOPS          120.07x faster than Python
