China's key weapons in its AI battle with the U.S. — massive Huawei chip clusters and cheap energy

It's good known that Chinese semiconductors designed for artificial quality cannot vie with the American steadfast Nvidia. Yet, China has managed to proceed processing highly precocious AI models, with galore being tally connected homegrown chips.

China's secret? A plethora of inexpensive vigor and elephantine spot clusters from the China's tech champion Huawei that are underpinning AI advances successful the country's contention against the U.S.

"China is striving for self-sufficiency crossed the AI stack, arsenic it sees AI arsenic a strategical exertion for nationalist and economical security," Wendy Chang, elder expert astatine the Mercator Institute for China Studies (MERICS), told CNBC.

With the world's second-largest system being chopped disconnected from definite tech owed to U.S. restrictions, and Beijing opting to shun Nvidia chips, questions person swirled implicit its quality to vie successful the tract of AI.

Despite these geopolitical challenges home exertion companies from Alibaba to DeepSeek person managed to make and merchandise precocious performing AI models, with galore being trained connected homegrown chips.

Nvidia's graphics processing units (GPUs) are seen arsenic the golden modular erstwhile it comes to the semiconductors required to bid and tally AI models and applications. But U.S. export controls person stopped Nvidia from shipping its astir precocious chips to China.

Under a woody with the White House this year, Nvidia was given the greenish airy to merchantability its H20 product, a downgraded spot designed for China, into the market. However, Beijing reportedly encouraged Chinese firms to eschew Nvidia products and alternatively usage chips designed for home companies.

In comes Huawei, 1 of China's astir celebrated exertion giants, which develops the Ascend bid of chips. But connected a chip-per-chip basis, Huawei does not vie with Nvidia. Instead, Huawei's vantage comes from its quality to nexus and link galore of these chips into high-performance "clusters" that tin vie with Nvidia.

One of those products is the Huawei CloudMatrix 384, which connects 384 of its Ascend 910C chips to present show to rival Nvidia's GB200 NVL72, 1 of its astir precocious systems. Nvidia's strategy uses 72 of its GPUs portion Huawei's merchandise uses 5 times arsenic galore of its ain Ascend chips.

"This strategy relies connected high-speed, perchance optical interconnects to determination information rapidly crossed ample clusters – a setup that doesn't require top-end chips and truthful suits China's existent strengths," Brady Wang, subordinate manager astatine Counterpoint Research, told CNBC.

The downside to Huawei's strategy is that utilizing much chips besides means importantly higher powerfulness consumption. And that's wherever China's vigor vantage implicit the U.S. kicks in.

"Solutions similar the CloudMatrix are little powerfulness businesslike than Nvidia systems, but present China benefits from its abundance of inexpensive energy," MERICS' Chang said.

"China has made monolithic investments successful greenish vigor including solar, upwind and more. It has besides been rapidly expanding its atomic vigor infrastructure. It tin truthful number connected inexpensive vigor erstwhile gathering retired AI infrastructure."

Beijing, arsenic good arsenic section governments, person looked to enactment this effort. A fig of cities crossed China, from Shanghai to the tech hub of Shenzhen, person offered subsidies oregon "vouchers" to trim the outgo for companies looking to rent computing power.

The Financial Times reported this week that immoderate section governments successful China are offering subsidies that chopped the energy bills of information centers that are utilizing home chips.

"Less advanced-process accelerators devour much power, but China is offsetting this with divers vigor sources — atomic and renewable options similar star — on with debased rents and financing, allowing it to money and tally large-scale clusters contempt inefficiencies astatine the spot level," Counterpoint Research's Wang said.

The question is, arsenic semiconductors for AI advance, volition Huawei and SMIC beryllium capable to support up with Nvidia and TSMC fixed the Chinese firms' restrictions connected entree to captious technologies?

"One of the cardinal constraints successful this strategy is China's capableness to nutrient capable chips domestically to marque up and support up with the spread successful capableness arsenic NVIDIA and others proceed to amended show arsenic well," Hanna Dohmen, elder probe expert astatine Georgetown's Center for Security and Emerging Technologies (CSET), told CNBC.

"China is moving hard to physique up its semiconductor fabrication capabilities and capacity; however, it inactive lags importantly owed to constraints imposed by U.S. and allied export controls connected semiconductor manufacturing equipment."
