Orders of magnitude (computing)

Orders of magnitude (computing)

This list compares various amounts of computing power in instructions per second organized by order of magnitude.

Scientific E notation index: -1 | 0 | 3 | 6 | 9 | 12 | 15 | 18 | 24

10-1

Slowest single sentient computation[dubious ]

  • 5×10−1 Speed of the average human mental calculation for multiplication using symbols circa 2000 B.C.[citation needed]

100

Reality speed frame of computation

  • 1 OP/S the speed of the average human addition calculation using symbols circa 2000 B.C.[dubious ][citation needed]
  • 1 OP/S the speed of Zuse Z1 first fully digital automated computer 1936
  • 5 OP/S world record for human addition set

101

Faster than human mental reaction computation begins[citation needed]

  • 2×101 Zuse Z3 1941
  • 6×101 Upper end of serialized human perception computation (light bulbs in the US do not flicker to the human observer)[dubious ]

102

Faster than animal perception computation begins[dubious ][citation needed]

  • 1.2×102 Estimated serial perception processing for a double dorsal brain.[dubious ][citation needed]
  • 2×102 Upper end of serialized human through put. This is roughly expressed by the lower limit of accurate event placement on small scales of time (The swing of a conductors arm, the reaction time to lights on a drag strip etc.)[dubious ][citation needed]
  • 2×102 IBM 602 1946 computer.

103

Kilo scale computing

106

Mega scale computing

  • 1×106 Motorola 68000 commercial computing 1979
  • 1.2×106 IBM 7030 "Stretch" Vacuum tube supercomputer 1961

109

Giga scale computing

  • 1×109 ILLIAC IV 1972 supercomputer does first computational fluid dynamics problems
  • 1.354×109 Intel Pentium III commercial computing 1999
  • 147.6×109 Intel Core-i7 980X Extreme Edition commercial computing 2010[1]

1012

Tera scale computing

1015

Petascale computing

1018

Exascale computing

  • 1×1018 It is estimated that the need for exascale computing will become pressing around 2018[2]

1021

Zetta scale computing

  • 1×1021 Accurate global weather estimation on the scale of approximately 2 weeks[3]. Assuming Moore's law remains constant, such systems may be feasible around 2030.

A zettascale computer system could generate more single floating point data in one second than was stored by any digital means on Earth in first quarter 2011.
