From an evaluation by Roy Longbottom, this interesting observation:

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.

It's not clear, but I think they were referring to the version 1 Pi - the newer ones are much much much faster.

And model 1 was even cheaper (but I guess these values should be indexed on inflation anyway)

They were ~$30 if I recall correctly. Inflation isn't quite that high...

I love looking that stuff up for perspective. 7 million in 1978 is $33 million today.
