Since the the first Bulldozers are rumored to not have any sort of speculative multithreading capability, the main focus seems to be in explicit multithreading (multiple threads, multiple programs, etc). Given that design focus it's doubtful that they forgot to include enough intercore bandwidth.
well anyways the benchmarks for inter core bandwidth is showing I7 to have 33.6 gbs while phenom II has 5.27 gbs that's a huge difference.

I'm little lost on what this "speculative multithreading" is suppose to be.

I though bulldozer was more about parallel threading.
