AMD "Piledriver" refresh of Zambezi - info, speculations, test, fans

And the frequency is not bottlenecked by architecture, all architectures have a hard time over 4GHz.

Completely wrong. Frequencies are bottlenecked by both the process (AKA transistor switching speed) and architecture (AKA number of sequentially placed transistors on critical path). And resulting processor frequency is a result of division of the first by the second. Bulldozer significantly shortens critical path and so it's frequency is much higher than 32nm Llano within the same power budget. Or you should expect ~4,1 Gz base clock for imaginery 6-core 45nm Bulldozer within the power budget of 1100T.
