All right guys, technically we’re
not supposed to compare human brains and computers as it’s not something that
you can technically do, Which is a little disappointing. Okay so, we can kind of compare the outputs of
brains and computers, So let’s at least do that. The world’s largest supercomputer is called “””K””” (as in 2011)
and it lives in Japan. It computes about four times faster than your brain and
has about 10 times the storage capacity. The human brain can process the equivalent of
about 2.2 mega flops (I love that word mega flop it sounds like - what my cat
does when she wants me to rub her belly). A mega flop is a million
operations per second so our brains are processing about 6.18 quadrillion
operations per second which I mean, when you see the stupidity of some people it’s
just shocking. By contrast the case of your computer does about 8.2 billion
mega flops which is a lot more. On the other hand the case supercomputer takes
about 10,000 watts to run by contrast
our brain takes about 20 watts to run and the “””K””” supercomputer cost tens of millions of dollars
to create whereas the human brain costs literally
nothing to create. The annual operating cost of the supercomputer is 10 million dollars and the annual operating cost
of your brain is hot pockets and Quiznos and then you look at it pound for pound, your cubic inch for cubic inch and your brain is like the size of both your
fists cell together

and the ‘’’’’’K’’’’’’ supercomputer uses 864 cabinets that are stretched out in a room (the size of a large airplane hangar) but it’s still really difficult to compare brains and computers because they work in completely different ways.

A computer has a program or a set of instructions that tells it what to do in addition to a memory that contains
all the data and
a processor that goes and gets the instruction implies them to
the data one at a time in a sequence, It’s all very orderly.

On the other hand a brain doesn’t have
separate processes in memory programs, each neuron in the brain can take in thousands upon thousands of inputs at a time and simultaneously independently
process them and spit out the answers plus it modifies its own functioning
on the fly all this is happening and it’s hundred billion or so neurons. The ‘’’’’’K’’’’’’ supercomputer doesn’t get
anywhere close to being that cool
so a supercomputer may be more powerful
than a human brain but the human brain
is still totally spring wins.
