U.S. export controls on Nvidia H20 AI chips enables Huawei’s 910C GPU to be favored by AI tech giants in China

Damage of U.S. Export Controls and Trade War with China:

The U.S. big tech sector, especially needs to know what the rules of the trade game will be looking ahead instead of the on-again/off-again Trump tariffs and trade war with China which includes 145% tariffs and export controls on AI chips from Nvidia, AMD, and other U.S. semiconductor companies.

The latest export restriction on Nvidia’s H20 AI chips are a case in point.  Nvidia said it would record a $5.5 billion charge on its quarterly earnings after it disclosed that the U.S. will now require a license for exporting the company’s H20 processors to China and other countries. The U.S. government told the chip maker on April 14th that the new license requirement would be in place “indefinitely.”

Nvidia designed the H20 chip to comply with existing U.S. export controls that limit sales of advanced AI processors to Chinese customers. That meant the chip’s capabilities were significantly degraded; Morgan Stanley analyst Joe Moore estimates the H20’s performance is about 75% below that of Nvidia’s H100 family.  The Commerce Department said it was issuing new export-licensing requirements covering H20 chips and AMD’s MI308 AI processors.

Big Chinese cloud companies like Tencent, ByteDance (TikTok’s parent), Alibaba, Baidu, and iFlytek have been left scrambling for domestic alternatives to the H20, the primary AI chip that Nvidia had until recently been allowed to sell freely into the Chinese market.  Some analysts suggest that H20 bulk orders to build a stockpile were  a response to concerns about future U.S. export restrictions and a race to secure limited supplies of Nvidia chips.  The estimate is that there’s a 90 days supply of H20 chips, but it’s uncertain what China big tech companies will use when that runs out.

The inability to sell even a low-performance chip into the Chinese market shows how the trade war will hurt Nvidia’s business.  The AI chip king is now caught between the world’s two superpowers as they jockey to take the lead in AI development.

Nvidia CEO Jensen Huang “flew to China to do damage control and make sure China/Xi knows Nvidia wants/needs China to maintain its global ironclad grip on the AI Revolution,” the analysts note. The markets and tech world are tired of “deal progress” talks from the White House and want deals starting to be inked so they can plan their future strategy.  The analysts think this is a critical week ahead to get some trade deals on the board, because Wall Street has stopped caring about words and comments around “deal progress.”

Domestic (China) Alternatives to Nvidia’s H20:
“There are several local Chinese companies that produce chips to compete with Nvidia,” said Brady Wang, associate director at Counterpoint Research.  In particular:
  • Baidu is developing its own AI chips called Kunlun. It recently placed an order for 1,600 of Huawei’s Ascend 910B AI chips for 200 servers. This order was made in anticipation of further U.S. export restrictions on AI chips.
  • Alibaba (T-Head)  has developed AI chips like the Hanguang 800 inference chip, used to accelerate its e-commerce platform and other services.
  • Cambricon Technologies: Designs various types of semiconductors, including those for training AI models and running AI applications on devices.
  • Biren Technology: Designs general-purpose GPUs and software development platforms for AI training and inference, with products like the BR100 series.
  • Moore Threads: Develops GPUs designed for training large AI models, with data center products like the MTT KUAE.
  • Horizon Robotics: Focuses on AI chips for smart driving, including the Sunrise and Journey series, collaborating with automotive companies.
  • Enflame Technology: Designs chips for data centers, specializing in AI training and inference. 

“With Nvidia’s H20 and other advanced GPUs restricted, domestic alternatives like Huawei’s Ascend series are gaining traction,” said Doug O’Laughlin, an industry analyst at independent semiconductor research company SemiAnalysis.  “While there are still gaps in software maturity and overall ecosystem readiness, hardware performance is closing in fast,” O’Laughlin added.   According to the SemiAnalysis report, Huawei’s Ascend chip shows how China’s export controls have failed to stop firms like Huawei from accessing critical foreign tools and sub-components needed for advanced GPUs. “While Huawei’s Ascend chip can be fabricated at SMIC, this is a global chip that has HBM from Korea, primary wafer production from TSMC, and is fabricated by 10s of billions of wafer fabrication equipment from the US, Netherlands, and Japan,” the report stated.

Huawei’s New AI Chip May Dominate in China:

Huawei Technologies plans to begin mass shipments of its advanced 910C artificial intelligence chip to Chinese customers as early as next month, according to Reuters. Some shipments have already been made, people familiar with the matter said.  Huawei’s 910C, a graphics processing unit (GPU), represents an architectural evolution rather than a technological breakthrough, according to one of the two people and a third source familiar with its design. It achieves performance comparable to Nvidia’s H100 chip by combining two 910B processors into a single package through advanced integration techniques, they said. That means it has double the computing power and memory capacity of the 910B and it also has incremental improvements, including enhanced support for diverse AI workload data.

China’s SMIC is manufacturing some main components of the GPUs using its N+2 7nm process technology although its chip yield rates are low, a source has previously said. At least some of Huawei’s 910C GPUs use semiconductors that were made by TSMC for China-based Sophgo, according to one of the sources and a fourth person.  SMIC is under its own export controls, which prevents it from accessing some of the world’s most advanced chipmaking equipment.
Huawei reiterated that it has not used TSMC-made Sophgo [1.] chips.  TSMC said it complies with regulatory requirements and it has not supplied Huawei since mid-September 2020.  Of course, the 910C GPU will be used in Huawei’s cloud service offering, which has ~ 20% of China’s cloud market
………………………………………………………………………………………………………………………………………………………………………………………………………………..
Note 1. The U.S. Commerce Department has been investigating work done by the Taiwanese contract chip manufacturing giant for Sophgo after one of its TSMC-made chips was found in a 910B processor.
TSMC made nearly three million chips in recent years that matched the design ordered by Sophgo, according to Lennart Heim, a researcher at RAND’s Technology and Security and Policy Center in Arlington, Virginia, who is tracking Chinese developments in AI.

Conclusions:

The U.S. Commerce Department’s latest export curbs on Nvidia’s H20 “will mean that Huawei’s Ascend 910C GPU will now become the hardware of choice for (Chinese) AI model developers and for deploying inference capacity,” said Paul Triolo, a partner at consulting firm Albright Stonebridge Group.

The markets, tech world and the global economy urgently need U.S. – China trade negotiations in some form to start as soon as possible, Wedbush analysts say in a research note today. The analysts expect minimal or no guidance from tech companies during this earnings season as they are “playing darts blindfolded.”

One thought on “U.S. export controls on Nvidia H20 AI chips enables Huawei’s 910C GPU to be favored by AI tech giants in China

  1. ByteDance, Alibaba and Tencent stockpile billions worth of Nvidia chips

    China’s top internet companies have stockpiled billions of dollars’ worth of Nvidia’s H20 artificial intelligence chips this year before the U.S. cut off shipments of the components in April, Nikkei Asia has learned.

    The H20 graphic processing unit (GPU) was specifically designed for sale in the Chinese market to comply with U.S. export controls, but ByteDance, Alibaba and Tencent began preparing last year for the possibility that Washington could curb their shipments, too, sources said. These chips, specifically designed to comply with U.S. export controls, are vital for AI applications, particularly inference tasks.

    ByteDance, one of the most aggressive buyers, and other firms reportedly placed rush orders worth over $12 billion, with several billion dollars’ worth shipped before the new restrictions took effect earlier this month, according to the report.

    The H20 is a downgraded version of Nvidia’s H100 chip, popular in China due to its lower power requirements compared to the original model.

    Earlier this month, Nvidia said it would take a $5.5 billion hit in the first quarter due to the new restrictions.

    With the new curbs, Chinese firms are looking at alternatives like Huawei’s Ascend chips and exploring ways to bypass the export restrictions, including setting up overseas subsidiaries, Nikkei reported.

    The stockpiling comes amid surging demand for AI computing power in China, fueled by the rise of applications like DeepSeek integrated into Tencent’s WeChat.
