Nvidia struck a surprising deal after convincing the president that H20 chips aren’t a national security risk. But whether the reversal is good or bad depends on who you ask.

Nvidia placed orders for 300,000 H20 chipsets with contract manufacturer TSMC last week, two sources said, with one of them adding that strong Chinese demand had led the U.S. firm to change its mind about just relying on its existing stockpile.

The stakes are high for Nvidia as it looks to restart China chip sales in the face of fast-evolving geopolitical tensions.
