Nvidia took a $4.5 billion write-off in its latest quarter on unsold H20 chips that it was unable to repurpose for other markets. If sales of these high-volume chips to China resume, a reversal of this write-off could boost earnings.

Nvidia will ramp up supply of Chinese-compliant H20 chips in the coming months and look to bring more advanced semiconductors to the world's second-largest technology market, Chief Executive Jensen Huang said at an event in Beijing.

American chipmaking giant Nvidia says it plans to resume sales to China of an artificial intelligence chip that’s become part of a global race pitting the world’s biggest economies against each other.
