The US government has banned AMD and Nvidia from exporting chips used to support artificial intelligence work to China. The ban affects Nvidia's A100 chips, often deployed in data centers to speed up the training of machine learning models, and its forthcoming H100 chip, while AMD has also received new license requirements that will stop its MI250 advanced AI chip from being exported to China. In a filing with the SEC, Nvidia said: "The US government has imposed a new license requirement, effective immediately, for any future export to China (including Hong Kong) and Russia of the Company's A100 and forthcoming H100 integrated circuit." According to Nvidia, the US government has said that the new license requirement addresses the risk of these chips being used for military purposes in China and RussiaNividia said it does not sell products to customers in Russia. Nvidia also stated in its filing that the new license requirement may impact its ability to complete the development of H100 in a timely manner or support existing customers of A100, and may result in it having to move certain operations out of China.

The US government has introduced and immediately started imposing a new rule that would restrict the export of computer chips used for supercomputers and artificial intelligence to Russia and China. NVIDIA has revealed in a SEC filing that the government has informed the company of the new license requirement affecting one of its current (A100) and one of its upcoming (H100) GPUs, which were designed to speed up machine learning tasks. The government apparently indicated to NVIDIA that the new license requirement will address the risk that the affected products may be used for military purposes by either country. As The New York Times notes, AI and machine learning are used for various applications that include weapons development and surveillance. "While we are not in a position to outline specific policy changes at this time, we are taking a comprehensive approach to implement additional actions necessary related to technologies, end-uses, and end-users to protect US national security and foreign policy interests."
