--" a higher count of L2 cache increases per-clock performance on average because it has less stalls waiting for system memory."
Which doesn't help much if you're limited by the speed of the core rather than the memory, as you're implying. A good prefetch will do more for you in most cases than the larger cache, which really helps only when there's a dataset to be worked on that fits in it (but wouldn't in the smaller one).
--"The design, the process, they all mesh together to give you a pretty lackluster performing processor. "
Again, you're completely missing the point of the PR ratings. A PR rated 2800 processor is going to perform pretty similar to aonther PR rated 2800 processor. By definition.
And no, you don't understand the difference between process and design issues.
--"So why did they elongate the pipeline if that was the goal of the design?"
Higher IPC and better scaling. We've already seen it definitely has the former. We won't be able to judge the latter for a couple years.
Remember how poorly the first P4s overclocked?
--"If the market is shrinking, it's AMD that's getting the shaft, and not Intel"
True enough, but you don't understand why. It's always been the case that market problems will effect AMD more negatively than Intel.
--"how is this "pushing it forward"?"
Intel's been pushing their ramping on the current core forward. Haven't really paid attention to Prescott dates.
--"BTW, AcesHardware posted news about the POVRay benchmark running on a 1GHz Itanium 2:"
They should have a good Operton benchmark up this week, judging by the hints they've dropped on their message board.
