China's Tianhe-1A is the fastest computer in the world, beating its U.S. and German rivals.
It's the first time a Chinese model has topped the bi-annual ranking of the planet's most powerful computers.
State media hailed the achievement as a milestone for the country's supercomputer industry.
The Tianhe-1A is nearly one and a half times faster than its closest rival.
With horsepower equivalent to 175,000 laptops, the Tianhe-1A can perform 2.57 quadrillion computer operations per second.
Housed at the National Supercomputer Centre in Tianjin, the machine will be used by scientists and will be made available to other countries.
