World’s top 5 super computers

Here is the list of top 5 supercomputers around the world - what these machines can do in a single day would take the average PC about 20 years.


  1. Tianhe-2

The winner and champion is the Chinese National University of Defense Technology’s Tianhe-2, or Milky Way 2. At a whopping 33.86 petaflops of computing power, Tianhe-2 is used to do largely whatever the Chinese government wants with it, with relatively few specifics of the massive machine’s workload available.
