Whats the CPU eqivalent of your brain

I read somewhere many years ago that the mind does something along the lines of 4 trillion calculations a second. Mostly they are unknown to us.

But for me, I would have to say i'm a X2 3800+. I can definitely hold two threads of constant processing.
 
Well I know it's some sort of mobile processor and my battery life is pretty good. Judging from the size of my general frame, I'm probably more of a "lugable" computer. The older crowd knows what I'm talking about.
 
What makes you say there is an equivalence? I can't do what a processor can, neither can a processor do what I can. For example, screwing multiple women at the same time....lol its Friday !
 
8088-2

If I remember correctly, our computing power is laughable compared to chips, but we pwn because of free association. We can derive an answer.


PS. I actually had a P-60 with the FDIV bug.

If you plugged a processor into a robot, it could...

That's probably off by a couple of orders of magnitude or so. I had some rough estimates a while back, the numbers were between single digit to tens of Billions, depending on neuron activity.

The calculation is fairly trivial, you simply compare the sum of neurons operating simultaneously and their switching rate versus transistors and their switching rate. Then you have a relative comparison of raw computation, of course not taking into account the efficiency, in terms of how it is used. However I don't recall the typical sum of active neurons and their average switching rate, but I do recall the number was in the Billions and it was a good estimate that was generally agreed upon.

The human brain is analog though. Neurons don't just switch 1's and 0's like a transistor. They have thousands of synaptic connections each, with each of those capable of transmitting hundreds of different "signals."

So a Core 2 Duo has 291 million transistors each one capable of switching between 1 and 0.

The human brain has 100 billion neurons with as much as 1 quadrillion synapses.

In short, a modern PC falls way way short of a human brain. I'd wager that a Core 2 Quad might be more powerful than the brain of a worm, but not by much, and certainly less powerful than the brain of your average fruit fly.
