Efficiency has to be the next step in GPU development before raw performance, surely. AMD at least tried to improve efficiency a little this gen with their chiplet design.

Efficiency as in "fps per watt" has improved every generation, it's just that they are increasing the performance so much that it overpowers the efficiency gains. It seems that enough people are happy to accept this kind of power draw if it means getting the highest performance possible.
