Alphas have very accelerated clocks but it doesn't translate directly
to efficiency- it's sort of like they are in a lower gear revving away
like mad.
PPCs have simpler instruction sets and an emphasis on a kajillion
registers, all general-purpose, and though they run a bit slower than x86
clock-wise they depend on the fact that they're easier for a compiler to
optimize for (less special cases and fancy tricks that aren't generally
useful, more registers which are more adaptable)
