Oh, they're more or less the same - the difference is that Intel's chips
have floating point which is comparable to their integer processing,
whereas AMD's K6's beat the pants off of Intel for integer, but lagged
way behind on floating point. 3DNow! was basically a quick fix to this
problem.
I suspect that we will see a similar effect on the K7 - 3DNow! will
probably won't make much of a difference, if the floating point is all
that it's hyped up to be. Anyone have one of these yet? (I'm waiting
for dual K7 mainboards myself.)
