hello am still new about laptops...I was wondering if all laptops' processor are all mobile technology? what will be the difference between a P4 and a celeron M?

a Pentium 4 is a full blown processor. While a Celeron is a processor with less cache (read slower) and the M means the chip was designed to be mobile lower power consumption, speed throttling, etc.

Centrino is also a mobile processor/platform meant for mobile use.

so does it mean that a P4 is still faster than a Celeron M, but the Celeron will just outlast a P4 in terms of battery usage?.......thanks for the reply pal....:)

Exactly...

Its like going with a 4 cylinder car for better gas mileage even though a nice v8 will beat it any day but suck the gas down. The universal trade off.

It depends on what the P4 and Celeron M processors are to give you a "which is faster". In most cases, the P4 would probably be faster but at the cost of power usage.

tkrabec pretty much explained the difference short and sweet, but I heard another explaination of the differences between desktop and mobile CPUs.

Think of a desktop CPU like a long conveyor belt. Lets say you want to send something up the conveyor belt only half way, because it is one long single conveyor belt the entire belt has to move which uses alot of power.

Think of mobile CPU's as multiple short conveyor belts that span the same length as the long desktop one and you want to send something up the belt only half way. Unlike the desktop CPU, the mobile CPU's only turn on the amount of conveyor belts to go the distance (halfway) instead of turning on the entire thing, by doing this they save power.
