ComfyUI has day 1 support for the new 50 series Blackwell GPUs.
Thanks to Nvidia ComfyUI has support for the new 50 series GPUs on launch day.
If you managed to get your hands on one you can see this discussion thread for how to get started. Be sure to check it often as I will keep it updated as much as possible and I expect there will be many performance improvements and updates over the next few months.
You need a pytorch build with CUDA 12.8 or newer, anything lower than that will not work. For how to get that see: the discussion thread
I'm using an NVIDIA 5070 Ti, but I used to run SDXL models on a 3060 Ti. I focused on speed improvements, using multiple LoRAs together and generating images with image-to-image (I2I).
Now, I’d love to use Flux with the same setup—or even better performance. I’ve been checking here every day, hoping for the official release of CUDA 12.8. Any idea when it might be available?
Any speed improvements for 40series card users?
