The ES-1 was #EvansAndSutherland's abortive attempt to enter the #supercomputer market. It was aimed at technical and scientific users who would normally buy a machine like a #Cray1 but did not need that level of power or throughput for graphics-heavy workloads. About to be released just as the market was drying up in the post-#ColdWar military wind-down, only a handful were built and only two sold.

Roy Longbottom Pits 1976's #Cray-1 #Supercomputer Against the #RaspberryPi
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 five watt power supply and is more than 4.5 times faster than the #Cray1." https://www.hackster.io/news/roy-longbottom-pits-1976-s-cray-1-supercomputer-against-the-raspberry-pi-single-board-computer-range-152bbe2d4111.html

How a Cray-1 Supercomputer Compares to a Raspberry Pi - Slashdot

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 guess there are a lot more than me who fell in #love with #Cray1 and now we can see benchmark comparing it to #raspberrypi
I have to say that the Raspberry do not have as cool case as the Cray.
