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 ?
AMD always pimped the Bulldozer out to be a single-threaded maniac. The only way I see that happening is if an ENTIRE module (2 cores and all) can process a single thread by itself. Two real cores working as one to chew through a single thread should be interesting. The Integer and floating point performance of a single module should make that interesting.
