eGPU + Desktop Hybrid

[dedakia]

Hi all,

 

I'm trying to create my own eGPU (with a twist) and would really appreciate some help!

I want a device that I can use for 2 different purposes:

1) As a eGPU to let me game using my Macbook Pro (via Thunderbolt)

2) An independent desktop computer capable of gaming (has its own CPU, RAM, HD)

 

The problem I'm having is figuring out a good way to interface the GPU with 2 different sources and switch between the two.

 

The current solution I can think of is creating a custom PCB which takes splits the GPU PCIe bus into 2, one of which is active depending on the orientation of a physical switch.

 

Is there a simpler way to do this that won't require designing a PCB?

 

Or is there any company selling this type of chip?

 

Thanks in advance

The practical solution is to physically move the GFX card itself.

While that is a simpler solution to implement, it is not a practical one as it would a lot of time and effort for switching, as well as two separate enclosures with their own power supplies.
