For the second year running China has the fastest supercomputer in the world. In the recently released new rankings, the world's fastest computer is the TaihuLight, housed at the National Supercomputing Center in Wuxi, China, and is capable of performing 93 quadrillion calculations per second, almost three times faster then the second-placed Tainhe-2. TaihuLight uses 41,000 chips, each with 260 processor cores, giving it 10.65 million cores. It has 1.3 petabytes of RAM, slightly less than Tianhe-2, and draws 15.3 megawatts of power. Taking third spot is the newly upgraded Piz Dain at the Swiss National Supercomputing Centre in Lugano, and in fourth is the US Department of Energy’s Titan supercomputer at Oak Ridge National Laboratory. It's the first time that more of the world’s top 500 supercomputers are Chinese than American: China now boasts 167 computers in the rankings, while the U.S. has 165, and third on the list is Japan, with 29.
