Evaluating the 1970’s Cray-1 supercomputer in opposition to the Raspberry Pi single-board pc vary #RaspberryPi @hacksterio « Adafruit Industries – Makers, hackers, artists, designers and engineers!
Developer Roy Longbottom, who has been personally benchmarking pc techniques giant and small for greater than 50 years, has revealed a have a look at how the venerable Cray-1 supercomputer stacks up in opposition to fashionable units of a significantly smaller scale: the Raspberry Pi household of single-board computer systems (SBCs) – hackster.io.
“In 1978, the Cray-1 supercomputer value $7 million, weighed 10,500 kilos and had a 115 kilowatt energy provide. It was, by far, the quickest pc on the planet,” Longbottom writes of the machine, designed because the flagship product of Seymour Cray’s high-performance computing firm. “The Raspberry Pi prices round $70 (CPU board, case, energy provide, SD Card), weighs just a few ounces, makes use of a 5 watt energy provide and is greater than 4.5 instances sooner than the Cray 1.”
