Unlike most designers, the second design of a series seemed to be the right one. The 7600 design lasted longer than any other supercomputer design. It had the highest performance of any computer from its introduction in 1969 till the introduction of the Cray 1 in 1976.
It was upward compatible, but had more PPUs.
It had a peak of 30 times faster than the 6600. This was a good trick, because the clock was not quite 4 times faster. The increase in speed was achieved with pipelining in every functional unit.
