US beats China to build world's fastest supercomputer that's one million times faster than a laptop

The US just took back the title for the world's fastest supercomputer. On Friday, the US Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee unveiled the'Summit' supercomputer that can deliver a peak performance of 200 petaflops, or about 200 quadrillion calculations per second. It managed to beat out the previous record holder that was China's Sunway TaihuLight supercomputer. Summit is 60% faster than the TaihuLight supercomputer, which could achieve a peak performance of 93 petaflops. The feat puts the US at the front of the top 500 supercomputers in the world -- the first time it has held such ranking since June 2013. Summit has been in development for several years now and is made up of thousands of chips.
