Assuming that each synapse processes one action potential per second and that these transactions represent the brain's computational output, then the brain performs at least one
quadrillion operations per second, almost a thousand times more than the best supercomputers.
In comparison, IBM's Blue Gene / P supercomputer, introduced a year ago, can be configured to process up to 3
quadrillion operations per second.
Assuming that the brain contains one quadrillion synapses processing on average 10 action potentials per second and that these transactions represent the brain's computational output, then the brain performs at 10
quadrillion operations per second.
