[The third-party measured performance of Tiangai 300 benchmarks against H200, and the measured performance of Tongyang TY1200 surpasses Thor T5000] On October 28, Tianshu Zhixin 2026 Media Open Day was held in Shanghai on October 28. Tiangai 300 opened a real machine demonstration for the first time, becoming the first domestic general-purpose GPU with measured performance reaching the H200 level. The third-party measured overall throughput of a single card reached 1.05 times that of the H200; the IXL144 super node integrated 144 GPUs, becoming the industry's highest-density single-cabinet GPU super node; the country's first GPU+XPU heterogeneous deployment AFD separation solution successfully ran through, reducing inference latency by 60%. The software stack "uses AI to develop AI", and Tianshu Zhixin has become the first domestic GPGPU manufacturer to have deep access to FlyDSL; Tongyang TY1200's measured performance surpasses Thor T5000, and it is the first time to implement GPU-accelerated physical simulation based on MuJoCo-Warp on a domestic end-side product.
