Standard Desktop graphics card usage on a laptop motherboard

funk_in_your_trunk · Sep 20, 2014

So the basic idea is being able to use some sort of an adapter to use standard desktop graphics cards in conjunction with a laptop.
I've been looking into this for a while and I've come across a few things like this:

however, it seems like it would bottleneck most mid-high to high end GPUs. Are there any other solutions? I also saw something about a Thunderbolt port if anyone wants to explain it that'd be great.

UPDATE: Please note I am not concerned with costs. It's not like I want to build one so i dont have to get a desktop: I already have one. This is purely for my own interest. I want to know if it is possible to do this without bottle necking the GPU - or atleast minimal bottle necking. And if so, how?
Thanks for the help guys.

Any of the methods there are would end up costing the same if not more than simply a better performing laptop.
They simply arent practical, thats why they are desktop cards. There was one method that could be considered "working" But it required external power, external PCI lanes, that rarely stayed connected, and it linked through USB.

If you want desktop performance, get desktop.

Possible? Yes.

Cost effective? No.
Better performance than a cheaper desktop? No.

Overall, you're turning a portable laptop into a badly performing desktop.

The only reasons to have a laptop are portability and space. Attempting to frankenstein a desktop GPU into a laptop deletes both of those benefits.
Leaving you with a badly performing, expensive, non-portable computer.

With a sufficiently high end GPU, yes, it will suffer compared to being in a dedicated desktop on a PCI-E slot.

The method I saw being used ran a 6670, and even that was bottlenecked by the external PCI bandwidth.
