Nvidia has developed three new chips tailored for China that aim to meet the region’s growing demand for artificial intelligence technology while complying with US export controls, according to leaked documents and four people familiar with the situation. 

The latest effort marks the second time in little more than a year that Silicon Valley-based Nvidia has been forced by new US regulations to reconfigure its products for Chinese customers, as it strives to maintain its foothold in one of its most important markets.

Nvidia is preparing to launch the new chips just weeks after the US restricted sales in China of high-performance chips that can be used to create AI systems, in the Biden administration’s latest salvo in a tit-for-tat tech war between the two superpowers.
