China's Iluvatar CoreX says its new GPU matches Nvidia's H200, narrowing the domestic chip gap.

Chinese artificial intelligence chipmaker Iluvatar CoreX claims that its new Tiangai 300 graphics processing unit (GPU) can match and even surpass Nvidia's H200 in real-world AI workloads. The claim highlights efforts by domestic players to close the technology gap with the US chip giant.

In a live demonstration for mainland Chinese media outlets on Wednesday, the Shanghai-based firm showed the Tiangai 300 outperforming the H200 in complex multimodal tasks, including text-to-image and text-to-video generation using frontier AI models such as Z.ai's GLM-5.3, according to a report by Chinese tech media outlet Xinzhixun.
