As we have said more than once, GeForce RTX 30 mobile graphics cards can vary greatly depending on the laptop model. The top-end GeForce RTX 3080 can have a TGP of 80 to 150 W or more, which has a corresponding impact on performance.
As it turned out, if you bought a laptop with a GeForce Ampere adapter with a lower power limit, this can be fixed. At least in the case of the ASUS ROG Zephyrus Duo 15.
This laptop is equipped with an RTX 3080 card with 115W TGP. Baidu forum users report that they have been able to flash the vBIOS of this mobile PC using vBIOS from other models, where the same adapter has a TGP of 150 watts. As a result, everything worked, and the video card became 18-20% more productive.
Of course, such manipulations in the case of laptops are very dangerous. Firstly, in mobile PCs, the capabilities of the cooling system are very limited, and secondly, you cannot just find out what total power the power circuits are designed for. Even if initially everything works fine, later the laptop may simply fail.
