Hi James, more numbers here.
Soft. AES implementation vs AES-NI implementation, 512 MB, ECB mode of operation, single core, buffer size 32kB, Windows: AES 128: 3873 ms (average calculated on 10 measurements) AES-NI 128: 1067 ms (average calculated on 10 measurements) Numbers are from my study, and they were also computed on pretty cheap notebook. The obtained results are similar to Intel's papers (there are many). I will try to implement ChaCha20 on Windows over the next few days. Boris Damjanović > Here are some numbers.
