Why isn't the 20-series graphics card supported? My 2080Ti 22G can't be used.
help
The RTX 20-series (sm_75, Turing architecture e.g., RTX 2060, 2080Ti) isn't supported because ComfyUI Nunchaku AWQ kernels, which optimize quantized models for faster inference, are designed for newer GPUs (sm_80+, like RTX 30-series). These kernels use features unavailable or less efficient on Turing, causing crashes or errors (e.g., data type mismatches) when loading AWQ models.
Switch to Non-AWQ Models: Use GGUF or fp8 quantized models to bypass AWQ kernel issues.
*obviously not possible here :)
Monitor for Updates: No fix exists yet, but developers may add sm_75 support.
I think Nunchaku team is planning to investigate this issue eventually, but there is no dates or guarantee.
Including RTX 20-series GPUs could significantly expand the Nunchaku user base and enhance the project reach so hopefully they will be interested.
是的，2070s直接运行会报错，秋叶启动器会停止。已经升级到最新的轮子。
