The difference in power consumption between 14nm and 14nm++ is actually quite high. From the page I cited:
<<A third improved process, "14nm++", is set to begin in late 2017 and will further allow for +23-24% higher drive current for 52% less power vs the original 14nm process. The 14nm++ process also appear to have slightly relaxed poly pitch of 84 nm (from 70 nm). It's unknown what impact, if any, this will have on the density>>
52% lower power is not just an incremental improvement. Typically that was achieved by a completely new manufacturing process.
