| # Pentium 100 97 61 - - |
| # PIII 75 77 56 - - |

| # AMD K8 54 55 36 20.7 9.57 |

| # (*) whichever best applicable. |
| # (**) x86_64 assembler performance is presented for reference |
| # purposes, the results are for integer-only code. |
| # (***) paddq is increadibly slow on Atom. |
| # |
| # IALU code-path is optimized for elder Pentiums. On vanilla Pentium |
| # performance improvement over compiler generated code reaches ~60%, |
| # while on PIII - ~35%. On newer ยต-archs improvement varies from 15% |
| # to 50%, but it's less important as they are expected to execute SSE2 |
| # code-path, which is commonly ~2-3x faster [than compiler generated |
| # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even |
| # though it does not use 128-bit operations. The latter means that |
| # SSE2-aware kernel is no longer required to execute the code. Another |
| # difference is that new code optimizes amount of writes, but at the |
| # cost of increased data cache "footprint" by 1/2KB. |
