P3 processor has only one SSE decoder so can execute only 1 sse insn per
cpu clock, but it has 3 mmx decoders (include load/store unit)
and executes 3 mmx insns per cpu clock.
P4 processor has some chances, but after reading:
http://www.emulators.com/pentium4.htm
I have doubts. Anyway SSE2 version of this code can be written better.
