INT8 Quantization Outperforms FP8 for MiniMax H3 on RTX 3090

A user on Reddit compared the performance of two different quantization methods for the MiniMax H3 model on an RTX 3090 GPU. The FP8 Scaled method took significantly longer to generate content compared to the INT8 ConvRot method with W8A8 quantization. Despite the speed difference, the user reported observing no discernible visual quality differences between the two methods, particularly for subtle movements in video generation tasks. AI
