02Good to know
The RTX 4080 Laptop 12 GB is an Ada Lovelace GPU with hardware FP8, so ComfyUI can compute Comfy-Org's FP8 files natively: small and fast. (Plain FP8 files use FP8 maths with the --fast fp8_matrix_mult option.) As a laptop GPU it runs at a lower power limit than desktop cards (60–150 W depending on the laptop). The memory verdicts are the same; speed depends heavily on how much power the laptop maker allows.
