How to get ComfyUI running on your new Nvidia 5090 or 5080.
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
Hi,
Are you using Comfy and 5090 in Windows or in Linux? I tried on windows and looks like there is no pytorch for Blackwell. Please advice if there is a chance to run Comfy and 5090 in Windows.
Thanks,
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?
