The power problem is solved by having cores more suited to a task. A CPU is completely general, but power inefficient. Dedicated HW is as efficient as it gets, but in the extreme is not flexible and only does one task well. With loads of extra silicon available, we can now use that for more specific engines/accelerators and of course not all of these would be active at once. So in a way the scaling / density does allow us to get more efficiency in some cases. The trick is finding the balance for a given process node.
