I don't know about SMC, but for other search related things I've dealt
with memory access is important, so it's reasonable to presume that
front side bus speed (and memory) and cache size are at least as
important as the clock rate. And, of course, the CPU architecture can
make a huge difference, too.

The logical explanation is that the franchise includes the stall,
the paper hat and a small gas-powered time machine."
