Notebook processors...Celeron, P4, or P4-M?

[Drakkon]

Currently have a 2Ghz celeron in a notebook...it can be upgraded to use any 1.5V 400Mhz buss socket 478 chip though.
I've been looking around though and theres really not too much of a difference between these chips are there?
I mean the celeron is running off a similar architechture of the P4 without the speedstep and and larger cache size?
And the P4-M is just made so it consums less power?
What would be the best buy for the $ and would i see any preformance gain (in programming and system preformance...this is NOT a gaming laptop) by moving to a p4 over the celeron?
and would i get more life (battery time) out of a p4-M than a celeron?

I don't think you would get any "noticeable" performance gain in general performance but there will be a slight boost. Battery performance is much the same between the two chips but Im not totally sure. My room mate has a Satellite 2410 with a P4M 1.8 and I have a 1410 with a Celeron 1.8 and we get pretty much the same battery performance. The only difference between our notebooks is the CPU. Many people bash the Celeron here, but for general day to day work (Not games) they are ok, and since the Mobile Celeron has 256K L2 Cache, it will actually perform much the same as the old Williamette base P4s. For what u are using your laptop for I would just stick to what you have. The only way you will really get better battery life is to move to a notebook with a Pentium M.

yeah it almost isn't worth the price to upgrade to any other 400mhz P4m
might as well just wait a year then get a new notebook
unless you can find one for a killer price or something
