A million times faster
From the press release "arrays of programmable resistors in complex layers"
At last an approximation to the way the brain is physically constructed (subject to how interconnections are made and pruned, of course). However even given that, speed is not by any means the most important factor. Human synapses operate in the millisecond range, but that hasn't stopped the human brain at best coming up with incredible ideas and discoveries (including this one). We ought to consider (as a minimum) [a] the evolution of the brain in the context of human cultures and [b] the truly vast amount of incredibly diverse information that each individual brain is exposed to from (possibly even before) birth to the point where the human becomes quasi-autonomous. So there's much more to human intelligence that the wiring and speed of signalling. Nevertheless this is a potentially important contribution towards competent simulation of brain activity.
