If this trend continues, AMD WILL go under and we'll be stuck with Intel... Not good.
Phenom II is only better than Bulldozer in terms of decode bandwidth, maximum theoretical throughput per core, a more adequately sized L1-I and L1-D Caches, a more responsive L2 Cache, and a significantly lower penalty for branch mispredictions.
Bulldozer has better Branch Prediction, more efficient decoders, better scheduling, better memory controllers, and a bigger L2 Cache. The reason Bulldozer failed is that these improvements aren't good enough to combat the huge increase in pipeline depth and a higher latency L2 Cache in lightly threaded workloads.
