What it is
Moore's Law, first articulated by Intel co-founder Gordon Moore in 1965, describes the trend in semiconductor manufacturing where the number of transistors that can be placed on an integrated circuit doubles roughly every two years. This exponential increase in transistor density has historically led to corresponding increases in computing power and reductions in cost per transistor, driving the rapid advancement of electronics.
This principle has been a foundational driver for the semiconductor industry, enabling the creation of increasingly powerful and smaller devices, from smartphones to data centers. While the physical limits of silicon-based chips are challenging its continued pace, its influence is still felt in the drive for smaller process nodes and innovations like chiplets. Deviations from Moore's Law can impact the rate of technological progress and investment in new fabs.
Why it matters
Moore's Law underpins the rapid progress in computing power and efficiency, impacting the performance and cost of all technology, from phones to AI.
