Tianhe-1a kicks an American computer out of the top spot. The Jaguar supercomputer built by Cray at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee is now only the world's second most powerful computer. That machine, powered by its thousands of Opteron cores, posted 1.75 petaflop LINPACK performance.
The system has 2.507 petaflops of computing power, draws 4 MW of power - enough to power several suburbs!
With the addition of the new supercomputer, China now has two of the three most powerful supercomputers in the world. The third most powerful one - previously in second place -- was the Nebulae supercomputer located in Shenzhen, which also uses NVIDIA's Tesla GPUs. It has a peak capacity of 1.271 petaflops in LINPACK.
