How a Cray-1 Supercomputer Compares to a Raspberry Pi
Roy Longbottom worked for the U.K. covernment’s Central Computer Agency from 1960 to 1993, and “from 1972 to 2022 I produced and ran computer benchmarking and stress testing programs…” Known as the official design authority for the Whetstone benchmark), Longbottom writes that “In 2019 (aged 84), I was recruited as a voluntary member of Raspberry Pi pre-release Alpha testing team.”
And this week — now at age 87 — Longbottom has created a web page titled “Cray 1 supercomputer performance comparisons with home computers, phones and tablets.” And one statistic really captures the impact of our decades of technological progress.
“In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1.”
