IBM says it has made a significant breakthrough in computer processors by creating a 2nm chip in its test lab.

The process เข้าเล่น slotxo used to make computer chips is measured in nanometers (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.

The computer chip industry used to use nanometers - one billionth of a meter - to measure the physical size of transistors. Today, a lower "nm" number is widely seen as a marketing term to describe new generations of the technology, leading to better performance and lower power.

IBM says its 2nm process can cram 50 billion transistors into "a chip the size of a fingernail" - up from 30 billion when it announced its 5nm breakthrough in 2017.

The end result should be another performance bump for computers in the coming years.

'A breakthrough'
Current high-end desktop chips based on the 7nm process, such as AMD's Ryzen processors, did not become widely available until 2019 - four years after IBM announced it had cracked the 7nm process.

But mainstream commercial chip-makers such as Intel and TSMC - which makes AMD processors - have already said they plan to build ultra-low nm chip plants in the next several years.

"This can be considered as a breakthrough," said Peter Rudden, research director at market intelligence firm IDC.
