Bulldozer's vision in Fred Weber's head(ex AMD fellow back in 2005) :
http://www.scribd.com/doc/7316303/CPU-Aug-05 (page 108)

When asked : "Q :What are the top three items on your dream list of CPU innovations?" ,Mr Weber(a man who actually was a driving force behind the whole Clustered MultiThreading in the first place;look at his presentations back in 2005) responded:
"FW : Well, I’m thinking a lot about the heterogeneous multiprocessing right now. The other area that is of great interest but there isn’t a solution for right now is how to best automatically, whether in hardware or software, use multiple threads in order to speed up programs that are not traditionally parallel. There are a bunch of techniques, such as run-ahead processing, being investigated. But there’s no obvious solution right now. "
Can you see the effects of the above quote in the bulldozer module diagram ?
