Well you could go on and on but simply put the wider the FSB and the higher the clock speed on the processor the more throughput you have at least potentially. So if you are say building a gamer and you want (potentially) the best of both worlds (though Intel is catching up) many guys go for the AMD Quad systems, wider FSB and quick clock. Liken a Dual core system to a two lane highway, liken a Quad to a four lane, more information(data) passing through. Bus and clock can compliment each other is set up properly, the higher the BUS # the better, likewise CPU.
I am looking at new laptops.
(1) Sometimes the BUS speed is given in Mhz and sometimes in MT/S; how do I compare these measures?
(2) How do I determine which BUS speed makes sense for which CPU speed?
