Moore’s law is the observation that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every 18 months.
Moore’s Law was first noticed by Gordon E. Moore who described the trend in 1965. Moore’s prediction has proven to be phenomenally accurate. The chart above shows the era of personal computing devices, and chips made by Intel and Motorola. The Xbox One game console now has a custom processor with a staggering 5 billion transistors.
The capabilities of many digital electronic devices are strongly linked to Moore’s law: processing speed, memory capacity, sensors and even the number and size of pixels in digital cameras. All of these are improving at (roughly) exponential rates as well. This exponential improvement has dramatically enhanced the impact of digital electronics in nearly every segment of the world economy. Moore’s law describes a primary driving force of technological and social change in the 21st century.
