Calculated from real file sizes plus working memory. How the numbers work.
02Good to know
ComfyUI supports AMD GPUs on Windows officially since v0.7.0 (January 2026), through ROCm. Memory works the same as on NVIDIA, so the fit verdicts apply. Some custom nodes are NVIDIA-only. RDNA 3 has no FP8 compute, so FP8 files save memory but give no speed-up. As a laptop GPU it runs at a lower power limit than desktop cards (up to 180 W depending on the laptop). The memory verdicts are the same; speed depends heavily on how much power the laptop maker allows.
