The CDC 7600 was the Seymour Cray-designed successor to the CDC 6600, extending Control Data's dominance of the supercomputer field into the 1970s
The 7600 ran at 36.4 MHz (27.5 ns clock cycle) and had a 65 Kword primary memory (with a 60-bit word size) using magnetic core and variable-size (up to 512 Kword) secondary memory (depending on site)
It was generally about ten times as fast as the CDC 6600 and could deliver about 10 MFLOPS on hand-compiled code, with a peak of 36 MFLOPS
In addition, in benchmark tests in early 1970 it was shown to be slightly faster than its IBM rival, the IBM System/360, Model 195
When the system was released in 1967, it sold for around $5 million in base configurations, and considerably more as options and features were added
Among the 7600's notable state-of-the-art contributions, beyond extensive pipelining, was the physical C-shape, which both reduced floor space and dramatically increased performance by reducing the distance that signals needed to travel.
