World’s smallest what? (Apr, 1980)
In 1982 (two years after this article was published) the Cray-XMP was one of, if not the, most powerful computers in the world. It had 16 MB of ram and in a dual processor configuration could hit 400 MFLOPS. It also occupied something like 50 square feet, used an ungodly amount of power and cost around $32,000,000 in today’s dollars.
By comparison, the Apple A6 processor used in the iPhone 5 is built using a 32nm process, so smaller than the lines in that picture. It has 1GB, or 64 times as much memory and the setting aside the dual core CPUs, the graphics cores alone hit about 25 GFLOPS or about 60 times the performance of the Cray. The A6 is about 97 square millimeters in area and costs around $17.50. And of course, it does this all with out Josephson Junctions or a cryostat.

World’s smallest what?
I haven’t checked, but somehow I don’t think the Guinness Book of Records has this one. Scientists at the IBM Thomas J. Watson Research Center claim they have made the world’s smallest experimental circuit elements.
