Vrieskist schrijft dat The Tech Report report een klein experimentje heeft gedaan. Ze hebben de snelheid van een athlon op 702 MHz en een FSB van 108 vergeleken met een Athlon op 728 MHz en een FSB van 104 MHz. De hogere busspeed blijkt belangrijker te zijn om de performance te verhogen dan wat extra MHz uit je Athlon te persen (open deur):
The first thing you'll notice here is that we're not talking about monstrous differences. Nonetheless, there are some significant gains to be made. The most important comparison, in my opinion, is between the 700/100 score and the 702/108 score. The higher bus speed manages a gain of 3.5% on demo001 and 3% on demo002, despite nearly identical CPU speeds. Not bad for 5 minutes messing with your GF card and BIOS.
The next thing to look at is how far we have to push the bus speed on the 7.0 multiplier before it surpasses the 6.5/108 combination. The 702/108 combo somewhat surprisingly pulls out a victory over the 728/104 combo. If you're one of those people who set the GFD's multiplier as high as the CPU would go, then pumped the bus speed up a few notches to really push the limits, take note here. You could very well be better off backing that multiplier off a notch and cranking the bus speed as high as it will go.
Finally, examining the scores from 700/100 through 756/108 is interesting, since it shows the overall effect the higher bus speeds have on performance. The results tend toward diminishing returns; the jump from 103 to 104 on demo002, for example, gives a .83 frame increase, while the jump from 107 to 108 only yields a .3 frame increase.
