Chinese AI Chip Startup Dongfang Suanxin Exits Stealth Mode with 3D Stacking Strategy

Dongfang Suanxin, a Chinese AI chip startup led by industry veteran Wei Shaojun, who also serves as vice-president of the China Semiconductor Industry Association, has emerged from stealth mode. The company launched a corporate website and social media account on Wednesday, marking its first public communication since its founding in 2024. Dongfang Suanxin is betting on two core technologies—"software-defined chips" and "3D stacked near-memory computing"—to produce ultra-high-performance computing chips using a fully domestic supply chain. This strategy aims to bypass US tech export controls and reflects a broader trend in the global chip industry toward 3D architecture as traditional scaling reaches physical limits. The move follows Huawei's proposal in late May of the "Tau Scaling Law," a principle for achieving equivalent transistor density gains through 3D innovation. Dongfang Suanxin positions itself as a new but formidable player in China's AI computing sector, joining giants like Huawei in pursuing self-reliance.
