Chinese chipmaker Iluvatar CoreX says its new Tiangai 300 GPU can match, and in some cases beat, NVIDIA’s H200 in real-world AI workloads, in the latest sign that domestic players are trying to narrow the gap with the U.S. giant. The newest claims come from a live demonstration for mainland Chinese media that happened on a Wednesday.
Tiangai 300 As A NVIDIA H200 Rival Using Its Own Benchmarks, While Third-Party Testing Shows A Slim Advantage
During the demonstration, the Shanghai-based firm ran text-to-image and text-to-video generation using frontier models such as Z.ai’s GLM-5.3. In one text-to-image test, the Tiangai 300 completed every task and managed 0.101 images per second, compared with an 87.5 percent completion rate and 0.086 images per second for NVIDIA’s H200. However, the Chinese chip did take 0.64 seconds longer to complete the task
It’s worth noting that Iluvatar CoreX’s claims are supported by a third-party test from state-backed Shanghai INESA, which found the Tiangai 300, unveiled in July, delivered 1.05 times the H200’s throughput under typical deployment conditions. Separate reporting from Wallstreetcn says the chip beat the H200 by 15 percent in mixture-of-expe...
