China’s AI Strategy Leans on Huawei Chip Clusters and Cheap Energy to Counter the U.S.

China has found a powerful workaround to the U.S. chokehold on advanced semiconductors — combining Huawei’s massive chip clusters with abundant cheap energy to accelerate its artificial intelligence (AI) ambitions.

While Nvidia remains the global gold standard for AI chips, U.S. export restrictions have cut China off from the American company’s most powerful processors. Yet, Chinese tech giants like Huawei, Alibaba, and DeepSeek continue to build large-scale AI models using domestically produced hardware.

At the core of this effort is Huawei’s Ascend series — less advanced than Nvidia’s GPUs individually, but competitive when linked together in vast, high-speed “clusters.” One example is the Huawei CloudMatrix 384, which connects 384 Ascend 910C chips to deliver performance rivaling Nvidia’s GB200 NVL72, despite relying on five times as many chips.

“This approach leverages high-speed interconnects to compensate for weaker chips,” said Brady Wang, associate director at Counterpoint Research. “It suits China’s strengths — large-scale engineering and manufacturing.”

The tradeoff is power consumption. Huawei’s architecture demands far more energy than Nvidia’s — but China’s cheap and plentiful electricity turns that disadvantage into an asset. Supported by investments in solar, wind, and nuclear energy, as well as local government subsidies, Beijing has created a favorable environment for energy-intensive AI infrastructure.

“Less efficient chips are sustainable in China because energy is inexpensive and government-backed,” said Wendy Chang of the Mercator Institute for China Studies.

Still, a structural weakness remains. Huawei’s chips are made by SMIC, China’s top semiconductor foundry, using older 7-nanometer tools that lag far behind TSMC’s cutting-edge technology. Export restrictions, especially on ASML’s extreme ultraviolet lithography machines, limit China’s ability to close that gap.

“China’s main challenge isn’t scaling power or hardware clusters,” said Hanna Dohmen from Georgetown University’s CSET. “It’s whether they can keep up technologically as Nvidia and TSMC push performance forward.”

For now, though, Beijing’s combination of Huawei’s hardware muscle and low-cost power is proving enough to keep China in the global AI race.

DeepSeek claims AI model trained for just $294,000, challenging U.S. rivals

Chinese AI developer DeepSeek has disclosed that its reasoning-focused R1 model cost just $294,000 to train—dramatically below the hundreds of millions reportedly spent by U.S. leaders such as OpenAI. The figure, revealed in a Nature article co-authored by founder Liang Wenfeng, is the company’s first public estimate of training costs and is likely to reignite debate over China’s position in the global AI race.

According to the paper, R1 was trained on a cluster of 512 Nvidia H800 chips over 80 hours. DeepSeek acknowledged for the first time that it also owns Nvidia A100 GPUs, which were used in preparatory phases before training shifted to the China-specific H800s. The H800 was designed to comply with U.S. export restrictions that bar Nvidia from selling its more powerful H100 and A100 chips to China.

The cost revelation is striking: OpenAI CEO Sam Altman has said foundational models cost “much more” than $100 million to train, though OpenAI has never published detailed figures. DeepSeek’s claim of drastically lower costs fueled January’s investor selloff in global tech stocks, amid fears it could disrupt the market dominance of Nvidia and other AI giants.

Skepticism remains. U.S. officials have suggested DeepSeek may have obtained H100 chips despite restrictions, while U.S. companies have questioned whether its development relied on model distillation—a technique where one AI model learns from another. DeepSeek has admitted using Meta’s open-source Llama models and said its training data may have included content generated by OpenAI systems, though it insists this was incidental.

DeepSeek defends distillation as an efficient way to cut costs and expand access to AI by reducing the enormous energy and resource demands of large-scale training. Analysts note this could accelerate the spread of competitive AI models outside the U.S., though questions about intellectual property and national security will remain central to the debate.

China investors stay bullish on Cambricon despite index reshuffle

Cambricon Technologies, often dubbed China’s Nvidia, faces more than 8 billion yuan ($1.1 billion) in passive outflows due to a quarterly rebalancing of the STAR50 Index, but analysts say investor confidence in the AI chipmaker remains intact.

The company’s stock, which more than doubled in August, exceeded the 10% cap for individual weightings in the tech-heavy index. Though Cambricon shares fell 14% last week on profit-taking and rebalancing fears, they have since rebounded 10%, hovering near record highs.

Valuations are eye-watering—Cambricon trades at 521 times earnings, compared with Nvidia’s multiple of 50—but Beijing’s push for tech self-sufficiency, the DeepSeek AI breakthrough, and large-scale investments by Alibaba, Tencent, and Baidu continue to fuel the rally.

“Maybe some investors will use it as a reason to take profit, but I don’t think that will affect the long-term trend,” said Shihao Li, analyst at CLSA. Gavekal’s Tilly Zhang added that optimism is growing that China’s AI sector has entered a “self-sustaining cycle of rising investment and higher profitability.”

Cambricon’s fundamentals have helped power the surge. First-half revenue jumped to 2.9 billion yuan ($407 million) from just 64.8 million yuan a year earlier, swinging to a 1 billion yuan profit. The company forecasts 5–7 billion yuan in operating revenue for 2025.

Still, risks remain. Some fund managers warn of a speculative bubble, while others argue that growth potential tied to China’s strategic need to replace foreign AI chips may justify lofty valuations.

Broader Chinese markets are riding the same wave. The CSI AI Index is up 60% this year, far outpacing the 15% gain in the CSI300, and the Shanghai Composite has hit levels not seen in a decade.

The spotlight now shifts to whether Cambricon can sustain profitability and meet surging demand for AI chips—critical to maintaining its role as the flagship of China’s AI boom.
