Is it though? I think having a good metric is really hard. For example i can have a neural net running on my smartphone doing recognition tasks. A task the brain is typically good at due to its neural net structure while the computer basically has to simulate the net. But still my smartphone can mark all the faces in a crowd multiple times over in a time i can not recognize even a single person. And that with a camera way beyond the capabilities of the human eye. Modern smartphone processors draw around 1 or 2 watt max. So is my phone more efficient at doing this? One could argue that my brain does other stuff at the same time like controlling heartbeat and what not but my phone has to keep the wifi, clock and so on too. The truly impressive part is the ability of the brain to do completely generic problem solving for basically everything; while running on 10 watt. With the added ability to learn a few activities to a really high level. Its is not efficient at doing a singular thing it is efficient doing everything at once.
