I know for Crafty, the PII/PIII is substantially faster than the equivalently
clocked K62/K63/Athlon.  A K62-450 is only something like 10% faster than a
PII-300 (IIRC.  It's probably a little more than that...) for Crafty.

Many programs prefer the AMD chips, however.  Rebel and CS-Tal I know prefer the
AMD chips quite a bit over the Intel ones.  For CS-Tal, at least, part of this
is due to the large and fast L2 cache.
