On November 17, 2012, the Tianhe-1 supercomputer developed by the National University of Science and Technology became the fastest computer in the world with a peak speed of 4700 trillion times and a continuous speed of 2568 trillion floating-point operations per second  Less than three years later, at the 2013 International supercomputer Conference held in Leipzig, Germany, on June 17, 2013, the International TOP500 Organization released the latest ranking of the world's top 500 supercomputers  The Tianhe II, developed by the National University of Defense Science and Technology, ranks first with a peak computing speed of 549 million million times per second and a continuous computing speed of 339 million million times per second
Compared with the American Titan supercomputer, which was previously ranked number one in the world, the computing speed is twice as fast as the latter
The computing speed of China's Tianhe-2 is obviously ahead of other supercomputers
