Cray's latest supercomputer uses AMD x86 processors with NVIDIA Tesla 20-Series GPU to create a supercomputer capable of more than 50 petaflops in computing power. A petaflop is a quadrillion (or a million billion) operations a second. MORE POWAHH.
The Cray XK6 is supposed to be the first 'general purpose' supercomputer that uses GPU technology and the first buyer is the Swiss National Supercomputing Center. The XK6 will range from $500,000 to $1 million and serve as further proof of the larger role GPUs are playing in computers. [Seattle Times]
