U.S. Officials Order Nvidia To Halt Sales Of Top AI Chips To China

Chip designer Nvidia Corp on Wednesday said that U.S. officials told it to stop exporting two top computing chips for artificial intelligence work to China, a move that could cripple Chinese firms' ability to carry out advanced work like image recognition and hamper a business Nvidia expects to generate $400 million in sales this quarter. Nvidia shares fell 4% after hours. The company said the ban, which affects its A100 and H100 chips designed to speed up machine learning tasks, could interfere with completion of developing the H100, the flagship chip Nvidia announced this year. Shares of Nvidia rival Advanced Micro Devices were down 2% after hours. An AMD spokesman told Reuters it had received new license requirements that will stop its MI250 artificial intelligence chips from being exported to China but it believes its MI100 chips will not be affected.
