1. Fujitsu K (Japan) – $1.2 billion
The K computer is the fourth fastest supercomputer in the world which has a theoretical peak speed of 11 PFLOPS.
The system which was named after the Japanese world “kei” means 10 quadrillion and it cost $1.2 billion to create.
In 2011, TOP500 ranked K the world’s fastest supercomputer, and in November 2011 the system became the first computer to top 10 PFLOPS officially.
Then in 2012, K was superceded by IBM’s Sequoia as the world’s fastest supercomputer.
The computer is located at the RIKEN Advanced Institute for Computational Science, and is 60 times faster than the Earth Simulator.
K costs $10 million a year to operate, using 9.89 MW of power, or the equivalent of almost 10,000 suburban homes, or one million linked desktop computers.
