Think of it like gears on your car. Your celeron is 1st gear, your Core2Duo is 5th gear. The Mhz/Ghz is your Rev counter.
In first gear at 3000rpm, you are going maybe 20-30mph. in 5th gear at 3000rpm your are doing 80. The speed of the engine doesn't determine how fast your are going, just how quickly the engine is turning.
Great analogy
