1.3gHz Celeron M vs 1.5gHz Pentium M

I'm looking at laptops and I'm having trouble choosing which processor I want. The laptop will be used ONLY for browsing the internet, doing word processing and chatting on AIM. Would the 1.3gHz Celeron be enough? Should I step up to the 1.5gHz? Would there be a noticable difference? Thanks

you just answered your own question.
 
Does Celeron-M have better battery life, worse, or the same? That might be a huge factor if you are going to be working on the go for many hours, or working on planes a lot and stuff.
 
come to think of it, why do you even need a new laptop when when a used, 500mhz laptop will do just fine?
 
Celeron M has noticeably worse battery life compared to the same model but with the Pentium-M chip installed. So I would go for the P-M not so much because of the performance difference but simply due to the battery life. Also note that with the reduced battery life, comes an increase in heat production. This means the cpu fan comes on longer, spins higher, and the overall system will literally feel hotter.

except that you can actually downgrade the speed of both the celeron m and pentium m to about 300mhz. that saves tons of power.
 
Even the "downgraded" Celeron M was outperformed by the faster Pentium M. Intel cut out some of the power savings features of the Pentium M when making the Celeron version. For reasonable performance with VERY GOOD battery life, look for the slowest Pentium M "Dothan" offering. At the same MHz the Dothan outperforms the Banias while using less power. Just opposite of Prescott versus Northwood. 😀
