Read the fine print... the definition of performance there includes relative
battery life too...
So... as an example if you have a 1.7 centrino that lasts for 2 hours with a
given battery, but the 2.6 P4M lasts only one hour with that SAME battery
(not the battery a laptop with the 2.6 would normally come with)... the
centrino effectively IF IT HAD 100% CPU UTILIZATION THE ENTIRE TIME could
have managed to process 30% more bytes, therefore - Higher Performance!
Marketing is so funny sometimes. This is the same kind of benchmarking that
was used with the Transmeta Crusoe processor when it came out originally, I
thought it was a bunch of crap then, and still think its a bunch of crap
now.
No user keeps 100% cpu all the time, lucky if its over 10%, so its pretty
meaningless. I'd look at other features, and budget, and not worry about
which. Most office type apps are more ram conscious than CPU conscious, so
long as CPU is at over 700mhz. And if you go with at least the 1.4ghz, even
on battery power it should stay over 700mhz.
Hope that helped!
