Iluvatar CoreX demonstrated the Tiangai 300 GPU against NVIDIA’s H200 during a live event, claiming superior performance in text-to-image tasks with 0.101 images per second versus 0.086 for the H200, though the Tiangai 300 took 0.64 seconds longer.

A state-backed third-party test by Shanghai INESA showed the Tiangai 300 had 1.05 times the H200’s throughput, but this represented only a 5% advantage, while other claims referenced comparisons against older NVIDIA models like the H100.
