That increasing slope was due to PCI/AGP overclocking. FSB increases do more for performance than multiplier increases. In other benchmark fests, the scaling seen is less between 1.8 and 1.7 than 1.7 and 1.5 relative to clock rate. When comparing FSB overclocks, Athlon actually has a higher scale factor. Athlon does not need FSB overclocks to go faster but, P4 needs them. That is why my Tbird is faster at 1425/150 than at 1466/133 overall.

Bzzzzzzzzzzzz... wrong answer. Sure the total bang you get between 1.8 and 1.7 is less than what you get when you compare 1.7 to 1.5... but that's NOT what I was talking about. When I ran my comparison I normalized the performance increase for the increase in clock speed... The delta performance over the delta frequency was ALWAYS more favorable for the P4 than the K7... frequently by 2X... These weren't overclocked chips either... these were vanilla configuration benchmarks from Anandtech 1.3GHz - 1.8GHz. Try again...
