"There have been some indications that Intel would be doubling much of the front end for HyperThreading."

I would think that everything to the trace cache would have to be doubled for hyperthreading to work. What I was referring to was computational resources. The P4 resources were optimized a lot for the expected instruction stream, and, except maybe for floating point, there just isn't a whole lot left over to extract a huge amount of performance with hyperthreading. At a guess, for STREAM-like programs that mainly move stuff around without a lot of computation, hyperthreading may show good performance increases. But for extremely computational intensive tasks, there may not be enough resources for hyperthreading to show much, if any, performance increase.
