FLOPS is floating point operations per second. I'm pretty sure the human brain doesn't do floating point calculations. :-)
Aye, I know what FLOPS means (that's why I used it)- but I've seen figures before where they made a general comparison- if the brain was a computer, it's computational power would be equal to X-amount of tera or peta FLOPS. I see other guys do it in MIPS sometimes- I think the figure I heard for that one (always stuck in my head) was 20 million billion MIPS for the brain. It's just a rough comparison. I found a couple of sources making this comparison for example:
Source (the original is a pdf file)-- We are within ten to fifteen years of being able to build computers that will match theinformation processing capability of the human brain, estimated to be 2 x 1016floatingpoint operations per second (20,000 teraflops), a speed 10,000 times faster than today'ssupercomputers.
