Unfortunately it's rather rare that notebook processor get compared
since it's quite a bit more difficult to fairly compare chips when
basically every component is changes between the two notebooks. That
being said, you can find a few comparisons here and there. First off
there is SPEC CPU2000. You can find the CINT scores here:
http://www.spec.org/cpu2000/results/cint2000.html
And the CFP scores here:
http://www.spec.org/cpu2000/results/cfp2000.html
Yes, there are a LOT of processors here, and VERY few of them are
Pentium-M scores (only two that I see, a Dell Precision Mobile
Workstation with a 2.0GHz "Dothan" Pentium-M and an HP Blade server
with a 1.0GHz "Banias" Pentium-M).
It works out that, clock for clock, the Pentium-M is about 20-30%
faster than the PIII for integer stuff and about 40-50% faster for
floating point stuff.
The P4 will perform similarly to the Pentium-M for most applications,
though it does so with MUCH higher power consumption. I really can't
see any good reason to go for a Pentium-4 processor for a notebook
unless you like brag about high GHz numbers. Here's a fairly recent
comparison of these two chips:

Note that the P4, if used in a laptop, would be somewhat slower than
what is tested in the above comparison since laptops would only have
half as much memory bandwidth as the desktop P4 system used.
