Orders of magnitude (computing)
||This article needs additional citations for verification. (March 2011)|
This list compares various amounts of computing power in instructions per second organized by order of magnitude.
- 5.2×100 World record for addition 
Faster than animal perception computation begins
- 2.2×102 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.)
- 2×102 IBM 602 1946 computer.
Kilo scale computing
- 9.2×104 Intel 4004 First commercially available full function CPU on a chip 1971
- 5×105 Colossus computer vacuum tube supercomputer 1943
Mega scale computing
- 1×106 Motorola 68000 commercial computing 1979
- 1.2×106 IBM 7030 "Stretch" Vacuum tube supercomputer 1961
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
Tera scale computing
- 1.34×1012 Intel ASCI Red 1997 Supercomputer
- 1.344×1012 GeForce GTX 480 from NVIDIA at its peak performance
- 4.64×1012 Radeon HD 5970 from ATI at its peak performance
- 5.152×1012 S2050/S2070 1U GPU Computing System from NVIDIA
- 80×1012 IBM Watson
- 100×1012 Estimated parallelized throughput of the human brain[dubious ]
- 1.026×1015 IBM Roadrunner 2009 Supercomputer
- 8.1×1015 Fastest computer system as of 2012 is the Folding@home distributed computing system
- 20×1015 IBM Sequoia Circa 2011
- 36.8×1015 Estimated computational power required to simulate a human brain in real time.
- 1×1018 It is estimated that the need for exascale computing will become pressing around 2018
Zetta scale computing
- 1×1021 Accurate global weather estimation on the scale of approximately 2 weeks. 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.
