Questions about hardware, SR macbook

[feyn-man]

1.This new one is 64-bit? or 32-bit?

2. The FSB is 800MHz now. But the memory is still 667MHz and somebody said you can't get performance improvement even use a 800MHz memory stick. Why? The lower speed of memory will not be bottleneck of the CPU?

3. Is the memory 64-bit or 32-bit? I mean how many data will CPU transfer in/out of memory once a time, 64-bit or 32-bit?

I'm a newer. I hope I have expressed my questions well. If not, just point out please.

1. 64 bit

2. The current Intel chipset may have a 800 system bus but the memory controller still operates at 667. That goes for any other PC laptop using Santa Rosa

3. Could you rephrase the question?

Could you rephrase the question?

Sorry for the poor expression.

I mean what kind of data transfer from memory to CPU? 64 or 32-bit?

That depends on the CPU or memory?

Actually, I believe neither. The chip set used regulates the bandwidth between the northbridge and the CPU. In any event, check out the following URL:

Hopefully, the info there will help answer you question.
