    No...
    Module is just a term to explain how AMD shares parts between physical cores.
    One module has TWO physical cores...HyperThreaded threads have nothing to do with TWO PHYSICAL CORES

    Of course AMD can price an 8 core to SB's 4/8...but wombat wasnt talking about competing, he was stating that basically thats what AMD's modules are.

    It's almost like buying a pack of batteries in twos instead of buying individual packs of batteries with just one battery inside...you save some space the packaging takes up. That's all a module does.

    8 cores, 8 threads. There is no option to turn "HT" off, and single threaded workloads are not going to skyrocket in performance like they would if you were running 4 threads on a 4/8 SB chip rather than 8.

    For example if you ran 4 threads of HyperPi on Bulldozer vs 8 for the most part all threads 4 or 8 will perform equally. If you ran 4 threads of HyperPi on SB it would be significantly faster than if you ran 8 threads of HyperPi.
