MiniMax H3 Local Test: RTX PRO 6000 Outperforms B300 by Almost Half in Inference Time

A developer benchmarked the MiniMax H3 video generation model across different hardware. Using Easy Cache for acceleration and upscaling from 352x640 to 704x1280, the RTX PRO 6000 took 55 seconds, while the B300 took 85 seconds.

The tester tried enabling Sage Attention on the B300, but incompatibility issues increased the time to 101 seconds. Testing Sol Attention yielded no speed improvements. The generated video quality appears consistent across both cards.
