The Jaguar system was previously outfitted with quad-core AMD Opteron processors -- and many others like it use AMD's chips. Four of the top five supercomputers are powered by AMD CPUs, including the former top dog, IBM's Roadrunner, which now sits at number two. In all, Jaguar contains 224,162 compute cores (up from 129,600), 300TB of memory, and 10PB of hard drive space.
The system boasts a theoretical peak performance of 2.3 PFLOPS, and a speed of 1.759 PFLOPS on the Linpack benchmark -- which topped the Roadrunner's 1.04 PFLOPS. Head over to Top500's website to see how Jaguar stacks up to many other supercomputers.
