Xingyun Integrated Circuit

Xingyun Integrated Circuit was founded in August 2023 and focuses on next-generation GPGPU chips for large-model inference, positioning itself as a fully self-developed GPGPU innovator in China. Its core team comes from Tsinghua University and leading global GPU companies, and its technical approach replaces expensive HBM with low-cost memory media such as LPDDR and NAND for ultra-large VRAM solutions, reducing VRAM costs by one to two orders of magnitude while achieving terabyte-level bandwidth through multi-die, multi-channel parallel design. In 2025 the company launched the Heiyi series of all-in-one machines, capable of running full large models at a price point in the RMB 100,000 range, and in September 2026 it completed a nearly RMB 800 million Series A funding round led by Puquan Capital under CATL and proprietary funds.
