The Biden administration said on Tuesday it plans to halt shipments to China of more advanced artificial intelligence chips designed by Nvidia and others, part of a suite of measures aimed at stopping Beijing from getting cutting-edge U.S. technologies to strengthen its military.
The rules, described by senior administration officials in a press briefing on Monday evening, restrict a broader swathe of advanced chips and chipmaking tools to a greater number of countries including Iran and Russia, and blacklist two more unnamed Chinese companies involved in advanced chipmaking.
The United States and China are locked in a years-long technology war, but the sweeping curbs released last October further escalated tensions between the superpowers.has made chips such as the A800 and H800 that walked right up the line of the previous rules to continue selling to China, and AMD.
The previous rules imposed a two-pronged test that measured both a chip’s computing performance and its ability to communicate with other chips, an important measure in AI supercomputers where thousands of chips are strung together to chew through huge amounts of data.created special chips for the Chinese market that retained the powerful computing capabilities but limited communications speeds to stay inside the previous rules.
The senior administration official said this rule was meant to prevent companies from trying to work around restrictions on full chips by using a technology called "chiplets," where firms could try to join together small pieces called chiplets into a large chip that violates the rules.to advance its chip industry, and analysts have said that Chinese companies could use the technology to evade U.S. restrictions.
