This much awesome Human Brain is....!
Let me tell you about an experiment that took place in 2013. Researchers in Germany and Japan used K, the fourth-most powerful supercomputer in the world at that time, to simulate 1 second of human brain activity.
The K supercomputer was a real monster. It had more than 700,000 processor cores and 1.4 million gigabytes of RAM.

Keep in mind that a typical supercomputer consumes large amounts of electric power that can mount up to several megawatts. The cost to power such a system is significant: for example, 4 MW at $0.10/kWh is $400 an hour or about $3.5 million per year.
Cooling is a huge issue as well. These systems produce so much heat that it needs complex water cooling systems to keep the cores from overheating.
Now back to the experiment. The K computer managed to simulate the interplay of 1.73 billion nerve cells and more than 10 trillion synapses. If this sounds like a lot, you have to know that this represents just 1 percent of the human brain's network.
The most interesting part for me was: that mighty computer that takes up a whole building, consumes $400 worth of electricity per hour and needs constant cooling and maintenance managed to simulate 1 second of “partial" activity of the Jell-O inside your skull in 40 minutes.
It took it 40 minutes!
That’s how awesome your brain is.
