The front-end in Bulldozer is pretty big, which says it got a lot of horsepower. Also it must have to feed the double hungry integer units in the module. In the 4 module/8core BD, up to 4 threads the front end can easy get one integer unit 100% buzy in each module with maximum Turbo, which mean very good performance in 1 to 4 threads. What happens with more threaded workload? Yeah, intel's Hyperthreading deliver at most 30% better performance, and means 130% performance per double-threaded utilized core. BD will deliver 160% per double-threaded utilized module. Here we see 640% from a 8 core BD, and 780% from 980x. However, I think the scaling will be much better on BD, and also higher clocked and more aggressive Turbo. The most inportant is what we don't know, and that is how efficient the architecure is.
Worth to notice is that we don't now if the 80%/160% numbers from AMD in multithreading is correct, we don't now how aggressive the Turbo function will be, and much depends on how optimized the software is for Bulldozer. A lot can be rewritten and better optimized for this new design.
