question about processor multipliers

if the bus speed is lower and the multiplier is higher, does that result in overall faster speed, regardless of the core speed? or does it not matter?

just wonderin

thanks!

 

Makes no difference to the speed of the cpu.
It does however affect FSB speed which is a measure of data transfer rate between the CPU and the northbridge (and is actually the CPU core speed x 4 (quad pumped)). It also directly links to memory and memory bus speed (which is dual channel).

eg.

cpu core 200 x Multiplyer 10 = cpu speed 2000Mhz(2Ghz) = Quad pumped FSB 800Mhz = 400mhz speed ram x 2 (dual channel) = 800mhz memory/memory bus speed
cpu core 100 x Multiplyer 20 = cpu speed 2000Mhz(2Ghz) = Quad pumped FSB 400Mhz = 200mhz speed ram x 2 (dual channel) = 400mhz memory/memory bus speed

Not quite sure if that's what you meant and I glossed over some things but you can see both examples have the same cpu speed but the second the FSB speed is much slower and will result in lesser performance.

 

thanks, that explained it pretty well
