Laptop eGPU rendering, how important is the transfer speed between the two?
I want to connect an external GPU to my laptop with a very basic setup (Like the cheap ebay ones). I plan to connect it to a PCIe x1 slot (by removing the wi-fi card), easy. Now, I can't completely comprehend how GPU rendering works. For the moment I know that before rendering starts, the 3D scenes get loaded into the GPU and they get rendered in there. Thus the only noticeable performance issues would the transfer speed of the scene because of the x1 PCIe connection... while the render performances should be fine. What am I missing?
