In the end of the 40’s IBM made the Selective Sequence Electronic Calculator which contained 12,500 vacuum tubes (25L6, 6J6, 6211) that could multiply two 10-digit numbers 40 times a second. The first versions of ENIAC used 19,000 vacuum tubes. The UNIVAC had 5200 vacuum tubes and consumed 125 kilowatts of power.
