There is probably an efficiency reason the human brain has 85 000 000 000(85 billion) neurons that operate with lossy compression operate in parallel drawing less than 20W of power.
- varelse 13y agoEach neuron in the human brain has ~10^4 connections to nearby neurons. This makes it an insanely data-parallel computer. This PoS is a task parallel nightmare.
- byerley 13y agoProbably more relevant is the greatly reduced clock speed (ignoring that the brain doesn't so much have a centralized clock - neurons only fire at <1k Hz compared to the ~2k Ghz processors used in clusters). The technology also seems somewhat incomparable. The purely chemical signal processing at the synaptic cleft presumably saves a lot of power.
- agumonkey 13y agomaybe it's more a throughput thing, if the brain is massively parallel, it's a giant pipeline with many things in flight all the time
