US Expands Chip Export Controls to Close Loopholes

The Biden administration releases updated chip export controls to close loopholes that allowed Nvidia's A800 and H800 chips — specifically designed to remain just below the original October 2022 performance thresholds — to be sold in China. The new rules adopt a more holistic 'total processing performance' metric and expand restrictions to 40+ countries to prevent transshipment. Nvidia is estimated to lose billions in Chinese data center revenue.
