Janek The tech rivalry between the United States and China has taken a sharper turn. In its most aggressive move yet to curtail China’s advances in artificial intelligence, the U.S. government has imposed strict new export restrictions on high-performance AI chips manufactured by Nvidia and AMD.
The move, announced Wednesday, is part of a growing campaign by Washington to prevent Beijing from using U.S. technology to train and deploy large-scale AI systems—an area viewed as central to future global power dynamics in defense, economics, and innovation.
What Do the New Export Restrictions Cover?
The restrictions specifically target Nvidia’s H20 chips and AMD’s MI308 series—cutting-edge processors designed for inference tasks, a critical stage in AI model deployment where trained models are used to make real-time predictions or decisions.
According to U.S. officials, these chips have become foundational to China’s rapid AI progress, particularly in sectors like cloud computing, surveillance, biotech, and military-adjacent applications.
The new policy aims to block further shipments of these chips to Chinese firms, unless specifically authorized under a case-by-case license. The Biden administration is also signaling more actions to come, with a May 2025 deadline for establishing global controls on AI chip distribution.
Why Now? The DeepSeek Factor
A key trigger for the latest round of restrictions was the unexpected success of Chinese AI startup DeepSeek. In recent months, the company has reportedly built powerful language models and multimodal AI systems using chips with lower processing thresholds, defying earlier assumptions that China required U.S.-grade hardware to compete.
DeepSeek’s rise has rattled both Silicon Valley and Wall Street—and provided fresh political fuel for U.S. officials pushing for stronger tech safeguards.
In a recently declassified report, the U.S. Congressional Committee on China identified DeepSeek as a case study in how Chinese firms may be circumventing export rules by innovating around hardware limits.
Nvidia and AMD Hit Hard
Financial markets responded swiftly. Nvidia and AMD stocks each fell roughly 7%, reflecting investor concern over potential long-term revenue losses and the wider chilling effect on U.S.–China tech trade.
According to analysts:
- Nvidia could lose up to $5.5 billion in revenue in Q1 alone
- AMD forecasts up to $800 million in lost sales
- Orders from Chinese cloud giants like Alibaba, Tencent, and ByteDance surged in Q1, in anticipation of the ban—totaling an estimated $18 billion
This massive pre-ban ordering spree underscores China’s heavy reliance on U.S. silicon and the urgency of its efforts to stockpile critical components before supply is cut off.
Behind the Scenes: Nvidia in the Crosshairs
While Nvidia has publicly stated that sales to China help fund its global R&D ambitions, sources close to the matter say the company has been quietly lobbying against tighter restrictions, arguing that China already has the capacity to replicate H20-level chips.
The White House, however, has shown little appetite for compromise.
Commerce Secretary Howard Lutnick made his stance clear:
“If they want to compete with us, fine. But don’t use our hardware to do it.”
U.S. officials have met multiple times in recent weeks with Nvidia CEO Jensen Huang, pressing for transparency around H20 architecture and global supply chains.
China’s Response: Pivot to Domestic Players
With access to U.S. chips drying up, China is accelerating its pivot toward domestic alternatives. Leading the charge are Huawei and Cambricon, which produce AI chips that—while not yet on par with Nvidia’s best—are improving rapidly.
According to a Citigroup analyst note, Chinese cloud providers originally planned to use Nvidia’s H20 chips for 50% of their 2025 AI compute capacity. With the ban now in place, those same companies are expected to transition rapidly to Chinese suppliers.
Beijing has also renewed calls for “chip independence”, pushing subsidies and policy support for homegrown semiconductors in a move that mirrors the U.S. CHIPS Act.
Global Implications
This latest development is more than a bilateral dispute—it’s a flashpoint in the global competition for AI dominance.
Key risks include:
- Tech decoupling: Accelerated separation of U.S. and Chinese technology ecosystems
- Supply chain disruption: Impacts across Asia, Europe, and the U.S. in chip manufacturing and equipment
- Security concerns: The U.S. sees unrestricted AI chip exports as a national security risk
Meanwhile, U.S. allies are being quietly urged to mirror Washington’s restrictions, with countries like the Netherlands (home to ASML) and Japan under pressure to tighten their export policies as well.
What’s Next?
All eyes are on May 2025, when the Biden administration is expected to unveil a comprehensive strategy for AI chip exports, including:
- Global licensing rules
- Updated security risk assessments
- Potential sanctions against companies that violate controls
At the same time, the U.S. Department of Commerce is expanding funding for export enforcement and trade compliance teams to ensure tighter monitoring.
Key Takeaways
- The U.S. has blocked AI chip exports from Nvidia and AMD to China
- Chinese firm DeepSeek accelerated policy urgency with surprise breakthroughs
- Nvidia expects a $5.5B revenue hit, AMD up to $800M
- Chinese companies rush to buy chips before bans take effect
- The AI chip war is escalating into a broader geopolitical showdown
