Its total graphics power (TGP, often called 'board power') is just 95 watts in the GS66 Stealth based on my GPU-Z logs. Naturally, the RTX 3080 Laptop GPU consumes less power than the desktop version. Its boost clock is also much lower, but it's underrated according to the utility GPU-Z (Opens in a new window), it maintained 1,350MHz to 1,400MHz in my 3DMark Fire Strike stress testing.
