Moore’s law wins: new chips have circuits 10,000 times thinner than hairs

IBM processors built at 7nm will be four times more powerful with up to 20bn transistors squeezed onto a single chip

Fears that Moore's law - which dictates the exponential growth of processing power - would falter this year have been allayed after IBM revealed processors with circuits just 7nm wide.

Moore's law states that every 18 to 24 months processing power will double and it has been steadily observed to be true since 1965, enabling the rapid technological progress over the last four decades.
