IBM says it has made a significant breakthrough in computer processors by creating a 2nm chip in its test lab.
The process used to make computer chips is measured in nanometres (nm) – with a lower number usually signifying a leap forward.
IBM claims its test chip can improve performance by 45% over current 7nm commercially available products.
It is also more energy efficient – using 75% less energy to match current performance, IBM said.
It claims the tech could “quadruple” mobile phone battery life, and phones might only need to be charged every four days.
