Does anyone know how similar/different are the SSE instructions
are implemented Athlon vs. P3/P4 chips?  Are the operational counts
the same or is one slower than he other?

An AMD compiler would be nice but it is not going to happen (opinion not
fact).  However an easy way for them to achieve this is to offer $$$$
to any compiler vendor to implement the 3Dnow instructions natively.
