Want to know about TDP
Hello guys, I hope you are doing good.
I need some help regarding my friends laptop GPU upgrade,
He has an Alienware M17x R3 laptop with 460m gpu and we want to upgrade it to 765m or 770m or any other better gpu is what we are looking forward to but we are having trouble in finding the TDP's of these gpu as some websites mix them up with "power consumption".
So I need to know the TDP of:
GTX 460M (current GPU)
GTX 765M
GTX 770M
And the fact that would it be fine replacing a GPU with the one having higher TDP then our current 460M....? Or will the laptop overheat...?
Thanks a lot in advance.

Thermal design power or TDP is the output heat in watts of a part.

The problem is it is determined based on average heavy load conditions. So a part may run over its TDP under the right circumstances while others may run well under it.

This heat has to be removed with a heatsink(attached to heatpipes in notebooks and many desktops)/fan(or blower).

This leads to issues when installing a new video card or cpu that will use the old cooler. If the TDP is too high, the cooler will not be able to remove heat fast enough and the part can overheat. The notebooks own power system also has to be able to supply enough power to this new card.

I would contact the notebook maker for a list of supported cards.
