    32bit CPUs can only access up to 4GB of RAM. 64bit goes way ahead. My question is; is the Macbook 64bit?

    Which MacBook? The current MacBook (Core 2 Duo)? ...Yes.

    Of course, RAM is limited by more than just processor bits.

    Yes, the current. I didn't know Macbooks were 64bit... I thought it was only the pro line.

    What, other than RAM, are the benefits of being 64bit?

    the only other advantages that I know of is that if programs are coded for it then working with large files will be faster.

    Yeah, being able to access 17,179,869,184 gigabytes or 16 exabytes of RAM is quite a big advantage!

    64bit integer arithmetic is also faster on a fully 64bit CPU. No real-world advantage yet, however.

    Definitely is!

    Intel 64 bit processors and the forthcoming 32/64 bit Mac OS X Leopard will fundamentally define Apple Mac's superiority and distinction over Windows PC.

    The applications will catch up with the processors surely enough.:)
