    AMD virtualisation question

    Can someone answer me a AMD CPU question please? When virtualising on a desktop with an AMD processor, how many logical processors would you end up with? I understand with Intel's Hyper threading you get each physical core split into two but cant find a straight answer for AMD.

    If I had a bulldozer for example with 8 logical cores, would I get 16 available to me or just 8? The AMD website talks a good talk but just cant get my head around this.

    Hope some of this makes sense to someone.
    Thanks

    Hyper threading gives two 'virtual' cores per physical core. Bulldozer/Piledriver etc effectively has 1:1 logical/physical. No equivalent to HT, but the modular core design in these CPUs mean a greater physical count than equivalent Intel products, (sadly with lower IPC).
