Do you expected much from ARM?? This is only a minor refresh useful in handset, a larger L2 could give better responsiveness, less bus activity and some advantage on few bench suites so loved by tech sites.
So nearly all the advantage is in the new process and in a better power management, no breaking news.

Qualcomm sports this core right now in the 600 serie, this say a lot about the strategic utility of the custom core that we'll see in 820.
