Intel Pentium (M) Processor Vs. Centrino

I googled this thread, seems useful. These links are pretty useful.

=========================

Before I go any further in my search for a new laptop (see below "is this too much to ask for"). I would like to ask: 1) Is the Intel Mobile Pentium-M the same processor as in the Intel Centrino package?

Centrino laptops are Pentium-M powered.

Just not with the wireless capabilities of the Centrino?

Correct. Centrino is a Pentium-M with "approved" wifi adapter.

My concern, will I get the same battery power from Mobile Pentium-M as I do with the Centrino?

A Centrino is not a processor. It is a Pentium-M with a Intel PRO/Wireless adapter on the i855 chipset. So yes, you will get the same battery life from a Pentium-M as you would from a Pentium-M. 2)

Also I sometimes see stuff like this: Intel Pentium M Processor 755. What's the deal with the 755?

And then they say it's eqivalent to a 2 GHz Processor. Intel has finally gotten away from the processor speed rating. With technological advances, slower (clock speed) processors can now handily ouperform their faster "competition". The 755 is not equivalent to, but is a 2GHz processor. It will handily outperform a P4 2GHz though most of the time. Think of it like your car. You can turn your engine at 3000RPM in 3rd gear and not go as fast and get worse mileage than you would in 4th gear. The engine works just as hard, but doesn't get the same amount of work done per revolution in the end.
