15 Huge Supercomputers That Were Less Powerful Than Your Smartphone







   





15. ENIAC

There’s no contest when comparing a smartphone to the first-generation ENIAC (Electronic Numeral Integrator And Computer), which was developed in 1949 and used to compute firing tables for the missile range at White Sands, New Mexico. Some even argue that it’s not a supercomputer, other than its size—ENIAC took up 15,000 square feet of floor space. Rather than transistors, the computer relied on vacuum tubes. And instead of entering commands via a software program, operators pulled switches and shifted cables around to complete the compute operation. Good luck trying to calculate your tip at the end of dinner with this monster of a computer.
