Summary
Huawei began mass shipments of its Ascend 910C AI accelerator in May 2025 and simultaneously unveiled the next-generation Ascend 920 — a direct Chinese response to Nvidia's absence from the market following H20 export restrictions.
What Happened
Huawei's Ascend 910C entered mass production and began shipping to Chinese customers in May 2025, filling the gap left by the US government's April license requirement on Nvidia's H20. The 910C is an architecturally novel dual-die design combining two Ascend 910B dies on a single package, delivering approximately 60% of an Nvidia H100's inference performance according to independent benchmark estimates. The chip is manufactured by SMIC rather than TSMC, which limits process node advancement but gives it supply chain independence from US-allied semiconductor manufacturers.
Simultaneously, Huawei unveiled the Ascend 920 — a more advanced chip built on SMIC's 6nm process node with over 900 TOPS of performance and HBM3 memory support. Bloomberg reported in September 2025 that Huawei planned to double 910C production output to approximately 600,000 units in 2026, suggesting the company was investing heavily in domestic AI chip supply chain capacity rather than treating the export control environment as a temporary condition.
Why It Matters
The 910C mass shipment marked a meaningful inflection point in Chinese semiconductor self-sufficiency. US export controls had been premised partly on a theory that Chinese AI development would be constrained by chip scarcity. Huawei's ability to ship hundreds of thousands of domestically manufactured accelerators — at a meaningful fraction of H100 performance — challenged that theory at scale. The medium confidence assigned reflects genuine uncertainty about production yields, actual delivered performance, and the extent to which Chinese hyperscalers were incorporating Ascend chips into their primary training infrastructure versus using them as supplementary capacity. The Ascend 920 roadmap suggested the gap to Nvidia would narrow further over the following one to two years.
