Was that doubling based on clock speeds, or actual processing power?
Clockspeeds are useless for comparing processors, even among processors of
the same type.
Case in point, I've seen a 350MHz P-II system that's more than 1.5 times
as fast as a 300MHz P-II system for NFS calculations, because the former
is a 100MHz*3.5, and the latter is 66MHz*4.5, making the memory access for
the first system a lot faster.
