The US Department of Commerce announced October 17, 2023, that it would ban exports of advanced AI chips including Nvidia H800, A800, A100, H100 and others, closing loopholes in prior 2022 restrictions. The ban also extends to semiconductor manufacturing equipment from Applied Materials, Lam, and KLA. The restriction is performance-threshold based (flops per square millimeter) and applies to data center chips exceeding specified density benchmarks. This materially narrows the addressable market for US AI semiconductor vendors and establishes a structural precedent for recurring export control interventions tied to technical performance metrics rather than one-time product bans.
