This is not a best way to compare it: brain neurons do orders of magnitudes less operations per second. Current Google's TPU clusters are 10 petaflops, with new ones being 1 exoflops. We can estimate 100Hz frequency for brain, so 100 * 10^11 = 10^13 "neuron operations". Let's estimate 1000 flops to simulate single neuron. So it gives us 10^16 flops for brain (aka 10 petaplops). I.e. Google's new deployments are more powerful than single brain.
- modzu 8y agoand what says that is the best way to compare it? neural networks don't model anything but the electrical synapse. there's much more going on (cf: chemical synapse). also speed isn't the holy grail: too fast in a human brain and you get seizures. why? it could be that as these systems scale up magical things happen. but it's a conjecture -- something we will discover, and not something we know.
