Apparently in a stunning revelation of sillyness, AMD
PR actually didn't know how many transistors Bulldozer had, and in fact, instead of the 2 billion transistors initially reported, it actually only has 1.2 billion.

AnandTech - AMD Revises Bulldozer Transistor Count: 1.2B, not 2B
To be totally honest, it does make more sense given the performance, but man, did AMD
PR ever screw up something bad.
Edit: Huh, just noticed I posted this in the press release section. Move it if it's not supposed to be here.
