benchmark: 4800K
In fact i make some improve in the NT patch (witch C code) that benchmark 5100K.
I send this code to Simon. This means that sse2 code its 4 times
slower that C code and dont help much. Searching in "Intel(r)
Pentium(r) 4 Processor Optimization" find that mmx and sse2 code
execute in parallel. We can make this:
...........................
one sse2 intruction
one mmx instruction
one sse2 intruction
one mmx instruction
...............................
and we can compute 6 words in parallel.
