Nvidia Defends H20 AI Chip Against Chinese National Security Concerns Amidst Ongoing US-China Tensions
Nvidia, a leading chip manufacturer, has countered allegations by Chinese state media that its H20 artificial intelligence chips pose a national security risk for China. The claims were made in an article published on WeChat by Yuyuan Tantian, an account affiliated with the Chinese state broadcaster CCTV, which asserted that the Nvidia H20 chips are neither technologically advanced nor environmentally friendly.
The article also alleged that the chips could perform functions such as “remote shutdown” through a hardware “backdoor.” In response, a Nvidia spokesperson stated, “Cybersecurity is critically important to us. NVIDIA does not have ‘backdoors’ in our chips that would give anyone a remote way to access or control them.”
Nvidia had previously refuted similar accusations regarding the inclusion of a hardware function for remote deactivation, or a “kill switch,” in its AI chips. Tensions between the U.S. and China over semiconductor export controls have been escalating in recent weeks, with Chinese state media portraying the H20 chip as inferior to Nvidia’s other chips while the company defends its products.
The resumption of H20 shipments by Nvidia reversed a ban on sales that was imposed by the Trump administration in April. The H20 chips, less advanced than Nvidia’s flagship H100 and B100 chips, were developed for the Chinese market following export restrictions on advanced AI chips implemented late last year.
The U.S.’s export controls on certain Nvidia chips stem from concerns that Beijing could leverage more advanced chips to gain a broad advantage in AI, including military applications. Chinese officials are reportedly pushing for the U.S. to ease export controls on high-bandwidth memory chips as part of a trade deal, potentially before a possible summit between U.S. President Donald Trump and Chinese President Xi Jinping.
Nvidia CEO Jensen Huang has supported Trump’s policies while advocating for export licenses for the H20 AI chip. Huang emphasizes that Nvidia’s chips serving as the global standard for AI computing benefits the U.S., allowing it to maintain market dominance and influence over global AI development.
China is a significant market for Nvidia, with the company taking a $4.5 billion writedown on unsold H20 inventory in May and forecasting that its Q3 revenue would have been $8 billion higher without chip export restrictions. Nvidia’s shares closed at $182.70 on Friday, up 1% for the day and 36% year-to-date.
