On Tuesday, chip designer Nvidia announced in an SEC filing that new US export restrictions on its high-end AI GPU chips to China are now in effect sooner than expected, according to a report from Reuters. The curbs were initially scheduled to take effect 30 days after their announcement on October 17 and are designed to prevent China, Iran, and Russia from acquiring advanced AI chips.
