There research show up that the bulldozer (fx8150/Opteron 6200) do have a broken integer divide unit.
the bulldozer performance per clock compared to a phenomII is lower because they fail its the "phenom1" effect.
i'm sure the next FX cpu is a bugfix and clock-speed-up stepping to fix the bulldozer.
