which Intel CPU's are 64-bit processors ?

Question

Hi,   I am deciding between the Inspiron 9400 with the IntelCore Duo T600 (2.16 Ghz) and the XPS-M170 with the Intel Pentium M 770 (21.13 Ghz).   Can anyone tell me are these both 64-bit processors? I know they should both run Windows Vista if there is 1Gb of RAM and a decent graphics card...   thanks for any help with this - I just want to be sure I can make the move to 64-bit mobile computing without having to buy a new laptop...   thanks   Philip

All of the new Intel Core Duo and Solo CPUs are 32-bit. They don't have EM64T extensions.

Since Intel's 64bit EM64T CPUs are not backward compatible with most earlier P4 systems, it's probably a safe bet the notebook chips, when they're released, won't be, either.

If you want a 64 bit PC-compatible notebook CPU, there's still just one game in town - AMD.

Those are desktop CPUs, though, and given most companies' experiences with them, I'd give them a very wide berth.
