I know very little when it comes to mobile processors, so some help would be greatly appreciated.

Which is the better processor T5500 Core 2 Duo; or T2700 Core Duo?

Next question is are they interchangeable as far as will they fit in the same socket?

As far as I can recall (without doing too much digging) the main differences are that the Core Duo processors are 32 bit dual core, single die chips and the Core 2 Duos are 64 bit dual core, dual die.

Here's some info from Wikipedia...

Quote:

The Core brand was launched on January 5, 2006 by the release of the 32-bit Yonah CPU - Intel's first dual-core mobile (low-power) processor. Its dual-core layout closely resembled two interconnected Pentium M branded CPUs packaged as a single die (piece) silicon chip (IC). Hence, the 32-bit microarchitecture of Core branded CPUs - contrary to its name - had more in common with Pentium M branded CPUs than with the subsequent 64-bit Core microarchitecture of Core 2 branded CPUs. Despite a major rebranding effort by Intel starting January 2006, some computers with the Yonah core continued to be marked as Pentium M. In 2007, Intel began branding the Yonah core CPUs as Pentium Dual-Core intended for lower-end mobile only computers, unlike the 64-bit Core microarchitecture CPUs branded as Intel Core 2 Duo (for higher-end computers) and also as Pentium Dual-Core (for lower-end desktops only). In short, the Core brand refers to processors with the "mobile" derivative of 32-bit Intel P6 microarchitecture (preceding the Core microarchitecture), whereas the Intel Core 2 brand refers to CPUs with the 64-bit Core microarchitecture. September 2006 and January 4, 2008 mark a discontinuation of many Core branded CPUs.

Thank you Dan that clears it up considerably.

I can't tell whether that's sarcastic or not!

Really, I meant it. That cleared it up for me, now I just have to decide if it would be justifiable to replace the CPU that is in it a Celeron M 430 with a Core 2.
