Computers, tablets and smartphones can more and more things these days. Fifteen years ago, they not powerful enough to movies or play high-definition games. Computer chip technology has at a fast rate. We can now movies on our smartphones and store huge amounts of data. IBM has it has made a significant breakthrough in microchip power. It has created chips that performance by 45 per cent. Its new chips also use 75 per cent less energy. This good for the environment, and means batteries will be more energy efficient. The technology could mobile phone battery life. We might only to charge our phones every four days.

IBM has greatly its microchips by reducing their size. The tech giant has a two-nanometre chip. Computer engineers use nanometres to the size of chips. One nanometre is just a billionth of a metre. A chip that is 2nm in size incredibly small. IBM says its 2nm processor can store 50 billion transistors on "a chip the size of a fingernail". Computer expert Peter Rudden said: "We have semiconductor manufacturers from 14nm to 10nm to 7nm, with 7nm a real challenge for some." He said IBM's new chip could artificial intelligence (AI). The chips could also data centres store more information. Data centres one per cent of the world's electricity.
