China warns local firms to avoid Nvidia H20 chips

Chinese authorities recently advised local companies to avoid using Nvidia’s H20 chips, especially for government or national security work, according to sources.

The guidance also applies to AI accelerators from AMD, though it is unclear if AMD’s MI308 chip was specifically mentioned.

Nvidia and AMD received US approval to sell lower-end AI chips like the H20 and MI308 to China, with a condition that 15% of related revenue goes to the US government.

Notices sent to Chinese firms questioned the need for using Nvidia H20 chips over domestic alternatives and raised concerns about potential security risks, which Nvidia has denied.

China’s restrictions currently focus on sensitive applications but may expand to more sectors. These measures reflect Beijing’s push to strengthen domestic chip production and reduce reliance on Western technology.

Nvidia said the H20 is not used for military or government infrastructure, while AMD declined to comment.

🧠 Food for thought

1️⃣ China’s technology localization follows a familiar playbook from previous campaigns

The current push against Nvidia H20 chips mirrors China’s broader strategy of gradually displacing foreign technology in sensitive sectors.

In 2019, Beijing issued directives for government offices to remove all foreign computer equipment and software within three years, targeting an estimated 20 million to 30 million devices in a phased approach1.

That earlier campaign followed a “3-5-2” replacement schedule—30% in 2020, 50% in 2021, and 20% in 2022—demonstrating Beijing’s methodical approach to technology transitions2.

The pattern shows China typically starts with government and state enterprise restrictions before potentially expanding to broader commercial applications, similar to how it previously restricted Tesla vehicles and Apple iPhones in certain institutions1.

This graduated approach allows Chinese companies time to develop alternatives while maintaining operational continuity, explaining why the H20 guidance remains targeted rather than an outright ban.

2️⃣ Domestic semiconductor gaps force China into selective rather than comprehensive restrictions

China’s measured approach to restricting American AI chips reflects the significant limitations of its domestic semiconductor industry.
