China beats America to the world's fastest supercomputer title - and it's faster than 338 MILLION ordinary PCs put together

China has built the world's fastest supercomputer - almost twice as fast as the previous U.S. record holder - with speeds equivalent to more than 338 million normal PCs. The Tianhe-2, which means Milky Way 2, was developed by the National University of Defense Technology in China's Changsha city and is capable of sustained computing of 33.86 petaflops per second. That's the equivalent of 33,860 trillion calculations per second, with the average everyday computer performing around 100 million per second (although some are faster and others may be slower). China's supercomputer Tianhe-2 has been declared the Top500 fastest supercomputer title. It was developed by the country's National University of Defense Technology and is capable of operating at the equivalent of 33,860 trillion calculations per second China's Tianhe-2 supercomputer, which means Milky Way 2, knocked the U.S. Department of Energy's Titan machine off the number one spot.
