According to this <http://www.nextplatform.com/2016/06/20/look-inside-chinas-chart-topping-new-supercomputer/>, it achieves 3 times the power efficiency of the x86 machines near the current top of the supercomputing league. According to the Ars article, the previous supercomputer king of the hill, “Tianhe-2 had been the world's fastest in six consecutive rankings, which are released twice a year”. So I think the record for staying the longest at the top still remains with the old NEC Earth Simulator, which was number one for maybe two years.
