Tianhe-2 is capable of operating as fast as 33.86 petaflops (one quadrillion floating point operations) per second. The winning computer, developed by China's National University of Defense Technology, put China at the top of the list in June.
The former winner, USA'S Titan which has a performance of 17.59 Pflop/s became second fastest one in the list.
Except for its computing chips, Tianhe-2 uses technologies that have almost all been developed and built in China, including the interconnect system, operating system, front-end processors and software.
Tianhe-2's predecessor, Tianhe-1A, took the first spot in November 2010, but it was overtaken by Japan's K computer six months later. Tianhe-1A is now No.12 on the list.
Sequoia, installed by USA is the third fastest supercomputer with a performance of 17.17 Pflop/s followed by Japan's K computer is the fourth one with 10.51 Pflop/s.
The Top 500 list, released twice a year since June 1993, is considered the authoritative ranking of the world's supercomputers.
