Supercomputers can store more information than the human brain and can calculate a single equation faster, but even the biggest, fastest supercomputers in the world [2] cannot match the overall processing power of the brain. And they are nowhere near as compact or energy efficient [3].

Nevertheless, IBM is trying to simulate the human brain with its own cutting-edge supercomputer, called Blue Gene [4]. For the simulation, it used 147,456 processors working in parallel with one another. IBM researchers say each processor is roughly equivalent to the one found in a personal computer, with one gigabyte of working memory.
