Even if k10 is able to compete with intel in the short term if they run into problems scaling the clocks again it will hurt them long term, the design needs to scale in performance - and raising the clockspeeds is the easiest way to achieve this, extracting ever more IPC gets increasingly costly in regards to die space/idle power consumption.
As I said IPC is only half the story.
