Apple's iPad 2 is as fast as a Cray 2 supercomputer from a quarter-century ago, Top 500 and Linpack co-manager Dr. Jack Dongarra said late Monday. At 1.5 to 1.65 gigaflops of computing power, Apple's tablet would compete with the eight-processor, 1985-era system despite being just a sliver of the size. Where the Cray 2 was the size of a washing machine, the NYT said, the iPad 2 can manage the same performance in the space of a large notepad.
