The first supercomputer became operational in 1976 and was able to perform a computing power of about 130 MegaFLOPS. This is not much, compared with the performance of a new home computer: A current Intel i7 processor is able to achieve more than 30.000 MegaFLOPS. The fastest supercomputer in the world is located in China, his name is Tianhe-2. On an area of about 700 square meters, Tianhe 2 achieves a computing power of more than 33,000 TerraFLOPS and consumes about 17000 kW of power.
