There's been lots written about this but this is my opinion. Bulldozer seemed to be designed under the assumption heavy floating point work would be done on the GPU (APU) which all early construction cores had built in. But no one is going to rewrite all of their software to take advantage of the iGPU that isn't present in existing CPUs and isn't present in the majority of CPUs (Intel) so it sort of smelt like Intel's itantic moment, only worse. I think they were desperate to see some near term return on the money they spent on buying ATI. ATI wasn't a bad idea for a purchase but they seemed to heavily overpay for it which probably really clouded management's judgement.
