A Look At Computer Power
1975 vs 2015

by Bill Raecke

As some of you may know, I worked in Information Technology for some time. When I entered the field, the most powerful computer in the world was the Cray-1 Supercomputer. Things have progressed quite a bit since then. I thought it would be interesting to compare computing power back then to what we carry in our pockets these days, so I did a little research. You'll find the results in the table below. Check it out.
