Travel Technology - Intel Core Duo and Duo 2

Can anyone explain the difference to me?

Does having one really DOUBLE battery life over having a Pentium M?

Eh?

Intel CD or C2D is a processor not a battery.

Processor type CAN affect battery life in a laptop. Quick looking about found tests where battery life was almost equivalent.

Also, Core Duo is on a 32-bit processor, while Core 2 Duo is 64-bit.

True.

Short answer - No.

From the Mobilemark benchmark tests ( http://www.intel.com/performance/resources/briefs/mobiletechnology.pdf )

Pentium M - 215 minutes
Core Duo - 298 minutes
Core 2 Duo - 306 minutes

For the long answer reference the above link.

It's a bit faster and has better power management. It can draw slightly more power in some cases but will equal or slightly increase battery life in almost ALL cases. IMO, get whichever one is cheapest. The 10% increase ain't worth the 30-40% savings you can find on equivalent Core Duo items out there. Also, for some of those, you can just drop in a Core 2 Duo chip anyway! The mac isn't one, sadly, but my Sony notebook is a snap to swap CPUs in. Once the 2.33 C2D drops enough, that's what I'll be doing.

Thanks!!

Now about processor speed. For example, I have a Pentium M 2.0 Ghz.
Is a Core Duo 2.0 the same speed? Core Duo 2 also?

How do the processor speeds match up?

I remember trying to compare Pentium 4 with the Pentium M/Centrinos before and having a similar problem...

They're not directly comparable... the designs are different enough that, clock for clock, the Pentium M will be faster in a few cases. Overall though, the Core Duo is a huge leap beyond and the dual processor capability means programs that can take advantage of the additional processor just fly. Core Duo CPUs run cooler IMO as well. I would never get a Pentium M over a Core Duo.
