Human brain uses 10^5 less power than von Neumann architecture, according to Caltech paper from ‘90s.
- metaphor 9y agoDo you have a specific reference? This Mead paper[1] suggests "...a factor of 10 million more efficient than the best digital technology that we can imagine"...which I interpreted as a gross approximation at the chip level assuming 10nm process, not considering any particular architecture, and doesn't include roughly 2-3 orders of magnitude reduced efficient at the system level.

- bobsil1 9y agoThat was the paper I was thinking of (thanks), but maybe the figure is from an IBM True North paper. I vaguely recall 10^-5 for brain efficiency, 10^-4 for True North vs. von Neumann.
