To avoid this, I have to set affinity to one core only which fixes the core to maximum frequency.
I think there is still room for improvement on that design, especially in how Vista manages threads. So for now, since PII is not for mobile, AMD avoids the huge penalty hit with the technique. But the technology is still there if the core isnt used at maximum potential.
