BAD HARDWARE WEEK

Finally, a truth on bad hardware
It can handle more than 50 billion instructions per second, about 17,000 times more than a top-of-the-line mainframe from 1970. Webb, in an interview with the Journal, said the new chip is designed to be better at the analytic workloads customers increasingly want to run.
Using power 7 , to be housed at the University of Illinois, IBM's Blue Waters will be the largest publicly accessible supercomputer in the world when it goes online in 2011, theoretically capable of achieving 16 petaflop speeds by connecting up to 16,384 Power7 nodes, although IBM said that initially the theoretical peak performance will likely be closer to 10 petaflops . Each hub chip  in Blue Waters enclosure will be connected with 48 optical connections able  for a total of 1,128 GB/s peak bandwidth . 8,9 Tbps.
