"The graphics processor maker revealed today at HPC 2010 China an incredible new supercomputer, built using NVIDIA's GPUs which support CUDA, a C-driven technology that allows for the implementation of parallel computing code on the GPU. The new supercomputer is named Tianhe-1a. It is located at the National University of Defense Technology (NUDT) in Tianjin, China and is fully operational.

With a total computing power of 2.507 petaflops, as determined by the LINPACK benchmark which solves a dense system of linear equations, China's new supercomputer is the most powerful one in the world.

And NVIDIA's real bragging rights come when the power consumption is discussed. By using GPUs instead of purely CPUs to fuel its calculations, the installation's power footprint is cut from an estimated 12 MW to 4.04 MW, saving enough electricity to power 5,000 homes a year."
