As CPU speeds increase, the performance does not scale linearly.

This means that the P4 will look worse and worse relative to Athlon as the clock speeds ramp up, assuming a fixed percentage delta in frequency (say 33%.)


Kind of a sweeping generality, Scumbria. Some tests scale more straight line than others (see new benchmark article below), and Athlon, as it moves up in freq., will not scale any more straight line than will P4.

New set of benchmarks:

Don't forget marketing & perception is half the battle. In that respect, AMD is not even in the ballgame.

Scumbria - Re"As CPU speeds increase, the performance does not scale linearly."

This is somewhat true for the same processors with the same subsystems. What you are failing to consider is that the AthWipe scales poorly while the P 4 scales well because of its new technology, including the deep pipeline. Cache designs and many other techologies also respond differently to frewuensy scaling. The difference between the two is likely to become become greater as frequency scales.

There are even some indications that RDRAM will gain an advantage over conventional memory systems as frequency increases.

1.5 could well equal much less than 2/3 of 2.0
