You mean *at the same clock frequency*, even, right? (That is, ignoring the fact that single core Prescotts will be available in 3.4, 3.6 and 3.8 GHz models.)

Interesting conjecture. Sounds reasonable.

I think the dual-core Prescott should perform worse than single-core in single-threaded operations
...
But a dual-core product will not be able to have the same volume of prefetching at all, leading to worse performance

In a single threaded app, won't the second core be more or less idle, leaving all available bandwidth to the active core? Wouldn't this core be able to the same amount of prefetching?
