Wind,

Your statements below are nonsense. The high bandwidth dual channel MC on P4 systems may offer some benefit, but this can also be implemented in DDR. (Not to say that Intel will be bright enough to do a two "channel" DDR.)

Athlon has a much larger L1 cache and larger L1/L2 effective size, which guarantees that it will scale better than P4 for CPU apps.

The only cases where Willy will scale better are for memory bandwidth limited apps like low-rez Quake (where it already is known to have an advantage), and the few SSE apps.

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.
