Don't want to.
First of all, AMD and Intel are not cross-platform, that is, you can not separate U, you have to change the motherboard.
Then ah, notebook motherboard it with desktop is not the same thing, not you say can change, you have to solve it still fit into the problem.
Stop there, and listen to what molds, AMD and Intel versions of the same model, are meaningless.
Old notebook, or AMD, the probability can die, sell not sell how much money.
In addition, not only Intel CPU can be connected to the graphics card. This involves an interface called lightning.
Lightning interface is now popular on the market is thunder 4, before the thunder 3, through this interface can be connected to the graphics card expansion dock, so as to achieve external graphics card.
Lightning interface, but also Intel patent, so in Intel CPU part of the notebook (especially high-end) is common, so you see "Intel CPU can be connected to the external graphics card", this conclusion is actually castration after non-universal conclusion.
The bottom line is money, man.
A new laptop with a Thunderbolt 4 port costs money, a graphics docking station costs money, and a graphics card costs money.
Of course, there are more elegant operation of external video card, through the M.2 switching, but not recommended to try.
