- INT8 ConvRot is a new quantization method natively supported in ComfyUI v0.27.0 (released July 1, 2026).
- It is particularly beneficial for GeForce RTX 20/30 series but also outperforms FP8 and FP8 Scaled on RTX 40/50 series.
- INT8 ConvRot uses INT8 encoding with a ConvRot (Convolution + Rotation) technique to distribute outliers, solving INT8's accuracy issues.
- It is faster than FP8 Scaled even on RTX 5090 (35% reduction in warm start time) and is expected to become the standard 8-bit format.
