Powered by Apple's ARM A9 chip, the SE is as fast as a Cray-2 supercomputer from thirty years earlier. At 1.5 to 1.65 gigaflops of computing power, the SE would compete with the eight-processor, 1985-era system despite being just a fraction of the size;  where the Cray 2 was the size of a dishwasher, the phone slips into a pocket.

The Cray-2 was predominantly developed for the United States Departments of Defense and Energy. Uses tended to be for nuclear weapons research or oceanographic development. However, the first Cray-2 (serial number 1) was used at the National Magnetic Fusion Energy Computer Center at Lawrence Livermore National Laboratory for unclassified energy research. It also found its way into civil agencies (such as NASA Ames Research Center), universities, and corporations worldwide. For example, Ford and General Motors both used the Cray-2 for processing complex Finite Element Analysis models of car bodyshells, and for performing virtual crash testing of bodyshell components prior to production.

iPhones are mainly used for posting selfies onto social media.

The Cray-2 cost $16 million, the iPhone costs £429 (including VAT).

At Volute, we design our websites’ administrator interfaces to be able to be edited using just a phone like an SE.
