What does the second number mean for processor speed?

by geofffeldman - 4/23/08 9:33 AM

I was browsing at Dells offers and options and came up with this:
Intel® Core™ 2 Duo T8300 (2.4GHz/800Mhz FSB/3MB cache) [agregar $240]
Intel® Core™ 2 Duo T5750 (2.00GHz/667Mhz FSB/2MB cache) [agregar $40]
Procesador Intel® Core™ 2 Duo T5550 (1.83GHz/667Mhz FSB/2MB cache) [Incluido en el precio]
Procesador Intel® Core™ 2 Duo T7250 (2.0GHz/800Mhz FSB/2MB cache) [agregar $100]
For clockspeed there are two numbers, ex. 2.0GHz/800Mhz, and the first is more or less three times that of the second. Now I know these are Duo but it makes no sense to me to pair a fast processor with a slower processor. So what does the second number mean?

Front Side Bus (FSB)

That second number is simply the Front Side Bus. This determines how fast your processor can 'talk' to your motherboard and the rest of the components. That first number is the overall speed of the processor which is the product of the FSB and multiplier; that's a little trivia if you're thinking of overclocking.

Basically you bigger the numbers for the both the better.

North bridge, South bridge

Note: CPU Speed is determinant by the North bridge
Note: location of Front Side Bus
