Is it possible to change the discrete GPU in a laptop?

Question

GPGPU

Good afternoon. Interested in the question, is it possible to change the discrete graphics card in a laptop to a more powerful model? For example, I have an NVidia GeForce GT 630M. Can I, for example, purchase a card from the GTX series and put it in instead of the existing one?

Answer 1

You can. But in addition to the cost of a new video card, you will also have to pay the cost of soldering

Answer 2

It depends on the model.
Let's say laptops created on a barebone basis, for example, Clevo, Eurocom, (in Russia they are sold under the DNS, RBT brands) provide for the replacement of any components by the owners themselves, including the replacement of video cards. Everything is easy to understand there.
In other models, it is so deeply soldered that it is not worth it.
Restrictions - by generation of video cards and system chipsets.
As well as cooling and nutrition. In laptops, unlike desktop computers, there is no large supply of power and cooling.
The simplest thing is to see what other video cards the manufacturer puts on your model. If such and such a video card is installed, then even if you replace it yourself, everything, including the power supply and cooling system, will most likely pull.
In some models - in MacOSX - there are also severe restrictions in the operating system.
