UNIVAC I used 5,200 vacuum tubes,[2] weighed 29,000 pounds (13 metric tons), consumed 125 kW, and could perform about 1,905 operations per second running on a 2.25 MHz clock. The Central Complex alone (i.e. the processor and memory unit) was 14 feet by 8 feet by 8.5 feet high (4.3 m × 2.4 m × 2.6 m). The complete system occupied more than 350 ft² (35.5 m²) of floor space.
Originally priced at US$159,000, the UNIVAC I rose in price until they were between $1,250,000 and $1,500,000. A total of 46 systems were eventually built and delivered.
