Chip designer Nvidia said new U.S. export restrictions blocking the sales of its high-end artificial intelligence chips to China had gone into effect on Monday after regulators advanced the timeline on the curbs from its 30-day period.

The company does not expect a near-term impact on its financial results from the accelerated timing, it disclosed in a filing on Tuesday.

The restrictions impact shipments of the company's modified advanced AI chips A800 and H800 - both of which it created for the Chinese market to comply with previous export rules. The Nvidia A100, H100, and L40S chips are also impacted by the curbs.
