Subject: Why is P4 less efficient than Athlon (or P3) for chess programs ?

Author: Ernest Bonnem

Does anybody here know the (somewhat detailed) technical reason ?
Chip architecture ?

On the average, for chess programs, a P4 running at frequency F is equivalent to
an Athlon at frequency F times 2/3.
Actually, it seems that this 2/3 ratio is no longer as bad for hi-end P4 (3.06,
3.0 GHz) or the Mobile Pentium : any confirmation and reason ?
