ComfyUI multi-GPU setups: text+VAE on one card, diffusion on the other
hurdurdur7 · reddit · 2026-08-28
A ComfyUI user shares their dual-GPU layout: on two 32GB cards, they load the text and VAE models on one GPU and the diffusion model on the other. Now adding an upscaler, they debate whether it should share the card with the diffusion model (since diffusion isn't needed during the VAE phase) and ask other multi-GPU users what layouts they enforce.
