Which is faster?

I'm trying to compare two laptops;

An older Toshiba A10-S177 with an Intel P4 M 2.2 Ghz

and a newer Toshiba A105-S2141 with an Intel Celeron M 410 1.46 Ghz
65 nm 1 MB L2 1.46 GHz 533 MHz

Granted there are many other factors, but generally speaking, which is
the faster CPU and why?

Thanks for your help.

Probably the Celeron M. This chip is based off the same Dothan core
as the Pentium M, which is *MUCH* faster than the P4 core at any given
clock speed. The difference in per-clock performance is probably more
than enough to make up for the ~600MHz clock speed deficit. It's
likely not going to be a big difference one way or the other, and some
apps will probably be faster on the P4, but on average my money would
be on the Celeron M.

Also the chip should probably consume a bit less power, though Intel
does cripple the Celerons somewhat in this regard by disabling some
power saving features. Still the more power-efficient design of the
core should result in somewhat longer battery life (all else being
equal), particularly given that you're comparing a chip made on a 65nm
process vs. one made on a 130nm process.

Not sure about the speed. Celeron M is based on a vastly superior PM
core, but it all depends on the extent to which Intel crippled it to
sell as Celeron. However the newer box might also provide better
chipset, video, etc. that also affect overall speed.
If you care about battery life, don't even touch P4 - it produces so
much heat that you might get your sensitive parts burned if you
actually plan to use it on your lap ;-)))))) All that heat is the
energy drained from the battery for nothing.

NNN
