Nvidia has ordered an additional 300,000 H20 AI chips from TSMC following a recent supply agreement. This move comes after the U.S. eased export restrictions, allowing Nvidia to resume chip exports to China. The H20 chip complies with US trade rules and is popular among Chinese tech companies like Tencent and Alibaba. Nvidia's decision aims to support developers and prevent reliance on competitors such as Huawei. The company’s shares saw positive gains following this announcement.
