They have modified the BIOS of the RTX 3080 Mobile integrated in the ASUS Zephyrus Duo 15 notebook and have managed to improve the performance by 20%
Laptops are limited in performance to avoid thermal problems and excessive power consumption. It seems that ASUS has further limited the consumption of the RTX 3080 Mobile in the RoG Zephyrus Duo notebooks. This adds to the controversy generated about the TGP according to the laptop's cooling system.

ASUS RoG Zephyrus Duo 15 improves performance by more than 20% by increasing TGP
Users of the Baidu social network (very popular in China) have managed to flash the vBIOS of the laptop's graphics. Through this flashing process, they have achieved that the TGP of the RTX 3080 Mobile goes from 115W to 150W. This allows the NVIDIA graphics get higher frequencies and higher tensions, improving performance.
In case you do not know what the TGP (Total Graphics Power) is the consumption of the graphics card. It does not refer only to the consumption of the GPU, but also of the memories, BIOS, controller and other components.
After the BIOS modification, the ASUS RoG Zephyrus Duo 15 under the 3DMark Time Spy has achieved performance between 12.590 points and 13.174 points. Notebookcek for this notebook with the factory BIOS has achieved between 10.619 points and 11.194 points. We are talking about a difference that ranges between 12% and 24%.
In Videocardz they correctly point out that these adjustments to improve performance can be negative. Voltage and frequency limitations are based on the laptop's cooling system. The manufacturer knows how long the design of heatpipes and fans can withstand. Such a modification could be a problem, as the laptop may not withstand the extra temperature generated.
We must bear in mind that laptops are more closed and more limited in cooling. On the desktop, graphics cards have heatsinks that support small frequency improvements through overclocking. This does not happen in notebooks, since it adjusts much more in the cooling, seeking to make the notebooks as light and thin as possible.
Indicate that in the process of modifying the BIOS we can suffer corruption. If the notebook experiences temperature problems and the BIOS modification is detected, the warranty is voided. We are talking about very serious problems.
