The chip also includes Radeon 780M integrated graphics.

ASUS
GraphicsNVIDIA GeForce RTX 5090 Laptop GPU, 24 GB GDDR7; ROG Boost 1647 MHz; 120 W (100 W + 20 W Dynamic Boost)

120 W is the upper power limit including Dynamic Boost: the extra 20 W is shifted to the GPU when the processor load is low and is not always available. The RTX 5070 Ti version of the same chassis is limited to 115 W, and the RTX 5060 and 5070 versions to 105 W.

ASUS		NVIDIA GeForce RTX 4060 Laptop GPU; 8 GB GDDR6; ROG Boost 2300 MHz; 125 W (100 W + 25 W Dynamic Boost)

2300 MHz is the 2250 MHz boost clock plus a 50 MHz ASUS overclock; ASUS says it measured this with FurMark in a 25 °C lab. The graphics chip is soldered and cannot be upgraded.

ASUS
Graphics switchingMUX Switch and NVIDIA Advanced Optimus

Advanced Optimus switches the internal display between the processor’s integrated graphics and the RTX 5090 without a restart. The MUX switch connects the display directly to the RTX 5090, removing the integrated graphics from the path in games.
