Question about ASUS ROG Zephyrus G16 RTX 5090

The RTX 5090 in a laptop does not run at the full desktop power of 575 watts, but significantly reduced, typically in the range of around 95 to 150 watts TDP, depending on the laptop configuration. This means that the GPU in the laptop is limited to a much lower power consumption in order to comply with thermal and energy-related restrictions.

NVIDIA has built various efficiency optimisations into the RTX 50 series for laptops, such as dynamic adjustment of clock rates and voltages, power and rail gating and fast switching between power states. This allows the GPU to adapt its performance depending on requirements and thermal conditions, thus offering a good balance between performance and energy consumption. The full performance of the desktop version is not achieved in the laptop, but the performance is matched to the available power and cooling system of the notebook.

To summarise: The RTX 5090 in the laptop only utilises a fraction of the desktop performance (approx. 150 watts instead of 575 watts), which is realistic and necessary for a notebook. Full performance is therefore only theoretically possible on the power supply unit, but is practically limited by the cooling system and the power supply.
