At its 2026 Media Open Day in Shanghai on October 28, the company, also known in China as Tianshu Zhixin, demonstrated its TianGai 300 GPU running live and said independent benchmarks showed its single-card throughput at roughly 1.05 times that of Nvidia's H200. The company has described the result as making it the first Chinese general-purpose GPU to match the H200 on measured performance rather than projected specifications, a distinction it has leaned on given how often domestic chipmakers' claims have rested on roadmaps rather than working hardware. The milestone sits inside a broader, unusually specific roadmap the company laid out at the start of the year, built around four successive architectures named for stars in the Big Dipper. Its Tianshu generation already outperformed Nvidia's Hopper-era chips, including the H200, through 2025, delivering about 20 percent higher average performance than Hopper on DeepSeek's V3 model while claiming over 90 percent effective utilization of its computing power. The next two architectures, Tianxuan and Tianji, are meant to match and then beat Nvidia's current Blackwell generation by the end of this year, with a fourth, Tianquan, targeted at surpassing Nvidia's upcoming Rubin platform by 2027. Iluvatar CoreX has also been converting that technical push into commercial traction. The company, which listed on the Hong Kong Stock Exchange in January, has built what it calls China's first mass-produced general-purpose GPU platform supporting both AI training and inference, and it recently unveiled a supernode system packing 144 of its GPUs and 18 CPUs into a single cabinet with more than 10 terabytes of memory. ByteDance has reportedly moved to buy at least 50,000 of the company's AI inference chips, a deal that would rank among the largest commercial validations yet for a Chinese GPU maker racing to fill the gap left by tightened access to Nvidia's most advanced hardware. --- Originally published by Pacific Post.
