Applicaton Benchmarks Windows98 SE
Using Windows 98, a Pentium III clocked at 750/150 MHz is clearly faster than a Pentium III 800/100, but slower than the top model at 133 MHz FSB.
To get the performance of a Pentium III 750/100, you can also get a Pentium III 600EB and run it at 150 MHz bus speed (675 MHz).
The same scenario. You can see quite well that 100 MHz FSB is not suited for high end computers any more. Using a 133 MHz CPU will give you the performance of the next speed grade of the 100 MHz pendant.
