Correct on the prefetch thing. I think I forgot about it because I seem to recall you or someone here explained the prefetch limits before HT could work well. And it is true prefetch is horrible on Athlons as demonstrated in a special test by Ace. Although one must wonder just how lower can the P4 go now that it is up to 50% the speed of an Athlon in gaming per clock, if you lowered its prefetch abilities.
Indeed they would need to improve it. But then again, shouldn't the core be improved? Is it it not too old-fashioned, and the only things really major in it are some components added? Sure there is a packing stage, but I've yet to see what improvements it brings, as you can count higher clockspeeds out. These are extra stages with extra work, not divided work.
Still, I think above all, the K9 must be a radical restructure (will be AMD's first ever since K6, considering the K7 was NexGen's design not their fruit), with a very long pipeline. Yes the K8 is performing excellently, and 64-bit could make it very much an Intel-killer, but eventually it won't clock far. It's still an old low-stage pipeline design. Intel's fruit may finally reveal its true future-proofness once the K8 wears out completely at the physical limits of 10-12 stage pipelining.
That's when Nehalem busts in.
