CPU upgrade puts Jaguar supercomputer at the top performance wise

The Jaguar supercomputer at the Oak Ridge National Laboratory was recently upgraded with new AMD processors that gave it enough performance to move up the top 5 supercomputers list. The Jaguar is a Cray XT5 supercomputer and is now the fastest machine in the world.

Jaguar previously used quad-core AMD processors and was upgraded to 6-core processors. The new upgrade gives the supercomputer a theoretical peak performance of 2.3 petaflops/s. The performance on the Linpack benchmark was 1.75 petaflops/second.

The second place computer on the list is the Roadrunner using dual CPU AMD power. The processors used in the Jaguar are AMD 6100 series parts.
