Yeah, not really.
These measurements mostly rely on the entire brain firing all at once, while a real brain does not do that.
- Razengan 7y agoGP did specify a generous range.
- ben_w 7y agoNot as broad as the range given in the summary at the top of the link, which says 10^12 to 10^28 FLOPS. The lower end (5e10 operations per Joule) is worse than existing hardware: Google’s first generation TPUs were reported as 40 W for 92 TOPS (8-bit) = 2.3e12 o/J, and Apple’s “Neutral Engine” cores are similar (I can’t find specific values for power use, but that was 5 TOPS (8-bit) and therefore plausibly between 1 and 10 watts).
- TeMPOraL 7y agoI wouldn't even call them "measurements"; last time I checked, the brain didn't run on IEEE 754.
- adrianN 7y agoI did my own measurements, I got about 0.01 floating point multiplications per second out of my brain.
- thatcat 7y agoIt's almost like your brain doesn't even have an FPU
- 6gvONxR4sf7o 7y agoIt does! But it's only good for counting up to 3 or 4.
