Chinese scientists have created a superfast analogue chip that can solve complex maths problems for advanced scientific tasks and artificial intelligence (AI) while using less power than conventional computing, according to a paper published this month.

The analogue device designed by researchers from Peking University uses memory chips made of resistive materials. With future improvements, it could perform calculations at a processing rate 1,000 times faster than top digital processors, such as the Nvidia H100 graphics processing unit (GPU), according to the team.
“Precision has long been the central bottleneck of analogue computing,” the researchers said in a paper published in the peer-reviewed journal Nature Electronics on October 13.
