12 # Performance in clock cycles per processed byte (less is better):
13 #
14 #               Pentium PIII    P4      AMD K8  Core2
15 # gcc           100     75      116     54      66
16 # icc           97      77      95      55      57
17 # x86 asm       61      56      82      36      40
18 # SSE2 asm      -       -       38      24      20
19 # x86_64 asm(*) -       -       30      10.0    10.5
20 #
21 # (*) x86_64 assembler performance is presented for reference
22 #     purposes.
23 #
24 # IALU code-path is optimized for elder Pentiums. On vanilla Pentium
25 # performance improvement over compiler generated code reaches ~60%,
26 # while on PIII - ~35%. On newer ยต-archs improvement varies from 15%
27 # to 50%, but it's less important as they are expected to execute SSE2
28 # code-path, which is commonly ~2-3x faster [than compiler generated
29 # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even
30 # though it does not use 128-bit operations. The latter means that
31 # SSE2-aware kernel is no longer required to execute the code. Another
32 # difference is that new code optimizes amount of writes, but at the
33 # cost of increased data cache "footprint" by 1/2KB.
