Oak Ridge National Laboratory's Titan Supercomputer is operating with improved energy efficiency due in part to the same upgraded technology in your child's video games.

"They do a lot of the same physics and on processors that are much more energy efficient than the ones we were using for scientific computation," said Jeff Nichols, ORNL's associate laboratory director for computing and computational sciences. "We took advantage of the gaming industry to give us 10 times more powerful processors and we only increased energy costs by half of what we were spending on specific systems today."

Titan is able to perform more than 17 quadrillion calculations per second.
