Huawei’s Ascend and Kunpeng progress shows how China is rebuilding an AI compute stack under sanctions

Huawei's New Year message highlights progress in its Ascend AI and Kunpeng CPU ecosystems, showcasing the development of Atlas 900 supernodes and increased adoption by domestic developers. Under sanctions, China is accelerating efforts to replace Western hardware in AI workloads, positioning Huawei as a vertically integrated AI compute vendor. Ascend's architecture, based on the Da Vinci architecture, and Kunpeng CPUs are evolving to build large systems compensating for weaker nodes with scale, networking, and software control. Huawei's strategy focuses on aggregate throughput rather than single-chip supremacy, emphasizing predictability and integration with its own AI frameworks. The Kunpeng CPUs provide the general-purpose compute layer for these systems, offering respectable throughput and potentially competitive performance in highly parallel workloads.

Cambricon targets 500,000 AI chips in 2026 as China accelerates domestic hardware push — low yields and limited HBM supply could threaten chip ambitions

Cambricon targets 500,000 AI chips in 2026 as China accelerates domestic hardware push — low yields and limited HBM supply could threaten chip ambitions

Cambricon Technologies plans to produce 500,000 AI chips in 2026, a significant increase from previous years, as China aims to boost domestic hardware production. The company faces challenges such as low yields and limited HBM supply, which could impact its chip ambitions. Cambricon relies on SMIC for manufacturing and targets major Chinese tech companies like ByteDance and Alibaba as key customers. The company's success in meeting its production goals will shed light on China's progress in developing a competitive AI chip ecosystem amidst global competition.

China starts list of government-approved AI hardware suppliers: Cambricon and Huawei are in, Nvidia is not

China starts list of government-approved AI hardware suppliers: Cambricon and Huawei are in, Nvidia is not

China has initiated a list of government-approved AI hardware suppliers to promote the use of locally developed AI processors in public sector organizations. The list currently includes Cambricon and Huawei but excludes foreign companies like Nvidia. This move reflects China's push for self-sufficiency in AI technology and semiconductor production. While Chinese companies like Alibaba and Tencent still rely on Nvidia's hardware for competitiveness, the government is incentivizing the use of domestic AI processors through energy subsidies. The challenge lies in whether China can meet the demand for AI processors domestically, especially with limitations on chip production capacity due to sanctions.

China bans foreign AI chips from state-funded data centers, report claims — crackdown would include removing Nvidia, AMD, and Intel chips from builds in early stages

China bans foreign AI chips from state-funded data centers, report claims — crackdown would include removing Nvidia, AMD, and Intel chips from builds in early stages

China has reportedly banned foreign AI chips from state-funded data centers, requiring the removal or replacement of Nvidia, AMD, and Intel chips. The directive aims to promote the use of Chinese-made silicon like Huawei, Cambricon, and Enflame. Projects less than 30% complete must remove foreign chips, impacting Nvidia's market share in China. The ban extends to Nvidia's H20, H200, and B200 models, tightening restrictions on U.S.-controlled technology. This move reflects China's push for data sovereignty and signals a shift in global AI supply chains amidst U.S.-China tensions.
