4070 Ti Super beats RTX 5070 2x on MiniMax H3 int8 in local inference benchmark
smellyelon · reddit · 2026-10-12
Testing on vast.ai under PCIe 4.0 x4, a Redditor found the RTX 4070 Ti Super runs MiniMax H3 at int8 roughly 2x faster than the RTX 5070, matching the 5070's best nvfp4 numbers (which OOMs at 15s×1MP). For Qwen Image 2.1, both tie on int8 generation but inpainting is 2x slower on the 5070, and its nvfp4 still trails 4070 Ti Super int8. Results compiled into an infographic for GPU buying decisions.
