Nvidia denies existence of 'secret access points' in their chips, addressing China's concerns regarding the security of their tech
Nvidia, a California-based leading producer of AI semiconductors, is finding itself in the midst of a complex geopolitical situation as trade tensions between the United States and China continue to escalate. The crux of the issue revolves around Nvidia's AI semiconductor exports to China and the U.S. export controls and licensing restrictions aimed at limiting China's access to advanced AI chips due to national security concerns.
The U.S. has imposed strict controls on Nvidia's high-performance GPUs, such as the A100 and H100, and more recently, on the modified versions designed for China, the A800 and H800, as well as the newer H20 chip. These restrictions have significantly impacted Nvidia's market share in China, with the company's dominance dropping from about 95% in 2021 to 50% in 2025, causing disruptions in Nvidia's AI chip sales and the broader semiconductor supply chains.
In an attempt to navigate these restrictions, Nvidia developed downgraded chips specifically for China. However, new rules have also banned these modified models, leaving the export of the H20 chip stalled due to backlogs and internal issues within the U.S. Department of Commerce, alongside ongoing debates among U.S. national security experts who advocate for even stricter controls given the potential risks these chips pose if used by the Chinese military or intelligence apparatus.
On the cybersecurity front, tensions have escalated as Chinese authorities recently summoned Nvidia to address alleged serious security issues found in the H20 chips sold in China. Beijing's Cyberspace Administration raised concerns about vulnerabilities and potential backdoors in these chips, demanding explanations from Nvidia. Meanwhile, U.S. lawmakers are proposing that Nvidia and others embed location tracking capabilities in their AI chips to enhance oversight, further illustrating mutual distrust.
Nvidia's CEO, Jensen Huang, stated during a visit to Beijing that the company remains committed to serving local customers. Huang added that he had been assured during talks with top Chinese officials that the country is "open and stable". However, the ongoing trade tensions and cybersecurity scrutiny present a significant challenge for Nvidia's operations in China.
The Chinese economy, beset by a years-long property sector crisis, poses another challenge to Nvidia's operations in China. Furthermore, heightened trade headwinds under U.S. President Donald Trump also pose hurdles to Nvidia's operations in China.
The issue of Chinese access to the H20, a less powerful version of Nvidia's AI processing units, has been a key point of contention. Jost Wubbeke of the Sinolytics consultancy stated that China is aiming to reduce reliance on foreign tech by promoting Huawei's domestically developed 910C chip as an alternative to the H20. However, the U.S. decision to allow renewed exports of the H20 to China could potentially tempt Chinese hyperscalers to revert to the H20, potentially undermining momentum behind the 910C and other domestic alternatives.
This dynamic reflects broader geopolitical and national security concerns surrounding technology dominance in AI semiconductors. As the situation continues to evolve, Nvidia finds itself in a delicate position, balancing the need to serve its customers in China with the demands of U.S. national security and trade policies.
