MiniMax H3 INT8 Benchmark: Native Implementation 45% Faster Than Fast-ROCM on RX 9070 XT
Mattnix · reddit · 2026-08-15
Reddit user Mattnix tested MiniMax H3 INT8 inference on an AMD Radeon RX 9070 XT, comparing ComfyUI's native INT8 implementation with PatientX's INT8-Fast-ROCM. At 1 MP resolution, the native implementation was 45% faster (31% reduction in generation time), contradicting documentation. The author calls for reproduction on other 9070/9070 XT systems.
