Many of the ufuncs like exp and log are hightly optimized kernels which use SIMD intrinsics where possible. The code can be found in various files in tthe numpy/core/src/umath directory, for instance here is the beginning of the SIMD exp function https://github.com/numpy/numpy/blob/f521ee5f9a9868f3
