1. Sunway TaihuLight
The Sunway TaihuLight supercomputer is almost three times faster than the next most powerful machine in the list.
Based in the National Supercomputing Center in the city of Wuxi, the Chinese system performs calculations to aid research and engineering work, ranging from climate modelling to advanced manufacturing.
Unlike most other supercomputers, the TaihuLight doesn't rely on Intel CPUs but instead utilises a custom ShenWei processor, a RISC CPU with 260 cores, and custom interconnects made in Wuxi.
Processor cores: 10,649,600
Max performance (Linpack benchmark): 93PFLOPS - quadrillion floating point operations per second
Power consumption: 15,371kW
