IBM's eight-core Power7 chip to clock in at 4.0GHz
 

We've got documents showing IBM going after a 10 petaflop system (peak) comprised of 38,900 eight-core Power7 chips with each chip running at 4.0GHz. This monster will have an astonishing 620TB of memory and 5PB/s of memory bandwidth. According to the documents, IBM will rely on a 1.30PB/s interconnect to link the systems and will feed them with 26PB of storage. As if that's not enough, IBM will offer an exabyte of archival storage
