Explanation of INT8 ConvRot (FP8 is no longer needed)
↗
For engineers building or deploying models, INT8 ConvRot offers reduced memory footprint and inference latency while maintaining accuracy, especially on older and newer NVIDIA GPUs. Its adoption may simplify quantization pipelines by removing the need for FP8 handling. As support spreads across frameworks, it could become a default option for 8-bit model distribution.

INT8 ConvRot uses row-wise scaling and the ConvRot quantization method to store INT8 weights.
It reportedly outperforms FP8 and FP8 Scaled formats on GeForce RTX 40/50 series and benefits GeForce RTX 20/30 series.
Support is being added in ComfyUI, Forge Neo, and related tooling such as Triton and PyTorch integration.
