Pentium 3s

What is the different between pentium M and Centrino? Which is the latest among these 2?

I have a IBM X31 which run on Centrino and a X40 which runs on pentium M. So Pentium M is latest?

1. Centrinos can be based on Intel's Core technology, and Core is much better than Pentium M, but without more detail I cannot say what you are referring to. Having looked into the laptops, they are a fair bit older. The X31 only has 256MB RAM, whereas the X40 has 512MB, so unless you are able to adjust these, I would advise the X40
2. Centrino is not a processor but a combination of mobile technology ie wireless card, Pentium m ect.
3. See Wikipedia for stuff like this, it will generally have good information (and a lot of detail). Centrino appears to refer to the "package", which initially contained a Pentium M chip. More recent Centrino packages will contain a newer Intel chip, not Pentium M. Follow these links for more info: http://en.wikipedia.org/wiki/Centrino http://en.wikipedia.org/wiki/Pentium_m Hope that helps.
4. Centrino mobile is the better than Pentium M. Pentium M is considered antiquated at this point.

6. As others say Centrino isn't a cpu is a platform or a combination of a cpu, chipset and wireless device. PentiumM was part of that platform. You will have to investigate which cpu is in each laptop and then do a little bit of research on the net to see which one is better.
7. Intel Centrino is the latest since it is being widely used by Compaq and HP laptops. Your IBM X40 has an older version of processor.
