basic FSB question

[beth]

hello, how are FSB and bus width interrelated?

1)Does the width of the bus determine the FSB?

2)Also, what multiplies the FSB to get the core clock speed?

 

[endyen]

The FSB is the bus width. It's width is the # of lanes, or paths it has.
On the other hand, it's band width is the total number of bits transfered per second. It is the product of bus speed, measured in cycles /second times bus width, in bits, times data rate.
The multiplier is the number that is achieved by dividing the "optimal speed" or "binned speed" of the chip by the FSB speed.

let's say I have 2 pcs; both pcs have the same frequency, but one uses 64-bit and the other 32-bit.

Does it follow that the 64-bit will have double the bandwidth of the other?
