Asynchronous, analog, spike-based, co-located memory. Closer NN sim than von Neumann architecture, orders of magnitude more power-efficient.
One human brain-equivalent NN on classic architecture costs ~$70M and uses ~100 houses worth of power.

In any case though my guess is that a human neuron accomplishes way more than a hidden unit in a NN so it may be fair to view that as a lower-bound.
