"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"

"The comment above was for the 2012 Pi 1. In 2020, the Pi 400 average Livermore Loops, Linpack and Whetstone MFLOPS reached 78.8, 49.5 and 95.5 times faster than the Cray 1."

Apart from the Cray-1, that whole section is also worth reading for some interesting insights into relative speed differences between various modern CPUs as well. (Though I do wish it was presented in table rather than narrative form, it’d be a lot easier to follow that way; there are also more detailed tables further down the page.)

There's a line in the Jurassic Park book where a character is made suspicious by an offhand assertion (by Nedry) that he is using a multi XMP system.

Rpi4s are nice, in a sense, because you can only rarely honestly claim that the speed of the system is holding you back. Most times, presumably, it's the efficiency of the operations you are telling it to execute.

Ok, do Pi 5 now
