Almost exactly the reverse of hyper-threading, where you have two of
everything to feed one core because a core can become stalled due to
waiting for input. Where this might have an advantage is to take both
sides of a branch then keep the one that is actually reached.

Analysis AMD lied about the true number of Bulldozer cores in some of
its Opteron and FX processors, it is claimed.
Mini-chipzilla boasted that, depending on the model, the chips had
either four, six, eight or 16 Bulldozer cores.
