> The synapses can fire up to one billion times per second — several orders of magnitude faster than human neurons — and use one ten-thousandth of the amount of energy used by a biological synapse.

So if this is true, and these chips function as expected, we should be able to simulate a human brain orders of magnitude faster than realtime using with less than 2mW.




That requires about 200W of liquid hydrogen cooling right now. Brain, some 20-40W of above room temperature water cooling. (Also evaporative.) Total efficiency equation is not yet favourable.
