Does anyone know a summary of SHA-256 performance on standard CPUs with dedicated SHA hardware? The Padlock engine has this but I don't know whether other CPUs also provide hardware support. I assume that on x86 the AVX instructions are as good as dedicated support: FWIW, Libgcrypt on an i5-2410M (64 bit) gives this: | nanosecs/byte mebibytes/sec cycles/byte SHA1 | 1.92 ns/B 496.5 MiB/s 4.42 c/B SHA256 | 4.42 ns/B 215.6 MiB/s 10.17 c/B SHA512 | 2.97 ns/B 321.1 MiB/s 6.83 c/B with AVX disabled: SHA1 | 2.27 ns/B 419.7 MiB/s 5.23 c/B SHA256 | 5.26 ns/B 181.1 MiB/s 12.11 c/B SHA512 | 3.61 ns/B 264.0 MiB/s 8.31 c/B with AVX and SSSE3 disabled: SHA1 | 3.27 ns/B 292.0 MiB/s 7.51 c/B SHA256 | 7.50 ns/B 127.1 MiB/s 17.26 c/B SHA512 | 4.68 ns/B 203.6 MiB/s 10.78 c/B We have no optimized SHA3 yet; for reference here are the numbers from the unoptimized version: SHA3-256 | 5.70 ns/B 167.3 MiB/s 13.11 c/B SHA3-512 | 10.66 ns/B 89.46 MiB/s 24.52 c/B Salam-Shalom, Werner -- Die Gedanken sind frei.
