BBC News - China claims supercomputer crown

"The title has gone to China's Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.

China's Tianhe-1A (Milky Way) has taken over the top spot from America's XT5 Jaguar at the Oak Ridge National Laboratory (ORNL) in Tennessee that can carry out only 1.75 petaflops per second. One petaflop is the equivalent of 1,000 trillion calculations per second."

...

Tianhe-1A is unusual in that it unites thousands of Intel processors with thousands of graphics cards made by Nvidia.
