Between 1983 and 1985 the fastest computer in the world was the Cray X-MP: Its two 105MHz processors combined with memory of 16MB they produced a performance of 1 million operations per second.
The price? 15 million dollars plus the cost of hard drives.
It was used for complex calculations and for first animations in CGI (including an animated intro by Marvel in 1986, with a silver and very agile Spiderman).
Today, an Apple iPhone XS is 1500 times faster and 15000 times cheaper. We generally use it for selfies.
