Shared GPU between Desktop rMBP 13" (2014)

Recommended Posts

So this probably a total noob question, and sincere apologies if that's the case. I spent the last couple days searching around in these forums.

I would like to time share my existing desktop computer's GPU with my rMBP (rather than buying and upgrading 2 GPUs) and I'm not sure how to approach this or if it's doable. I'd like to drive my internal screen on the rMBP in Win7 Bootcamp. Desktop motherboard is a Gigabyte: GA-Z68MX-UD2H-B3.

1. Is it even possible to skip a separate enclosure and house the GPU in the desktop itself? Using the existing PSU and a slot? Assuming that I will use only one computer at a time, but in the same location (odd circumstances I know).

2. I assume I need an adapter like a Sonnet. Is there anything comparable but cheaper without the enclosure? Again, see #1 about leveraging the desktop case and PSU instead.

3. If I did use an enclosure like the Sonnet, would I be able to connect it to either desktop or laptop?

Thanks

That will not work! You would need a sth like a PCIe Y-riser that can be plugged into one GPU and two systems. I don't think that sth like this even exists.

Ahh OK thanks. That's unfortunate. Guess I end up cannibalizing my desktop for it's GPU then :)

The new ViDock DIY supposedly has many different adapters to allow you to connect one enclosure to many different computers. They posted a picture on their facebook page yesterday about the setup. Here's a link if you wanted to check it out:

(It's the second soonest post they had, the one with How ViDock DIY connects to any form factor computer).

2. Please read http://forum.techinferno.com/enclosures-adapters/7205-us%24200-akitio-thunder2-pcie-box-16gbps-tb2.html

3. Your Thunderbolt eGPU implementation can be attached to any notebook or desktop with a Thunderbolt port. Your GA-Z68MX-UD2H-B3 desktop systemboard has no Thunderbolt port so would require adding one using a PCIe slot: Amazon.com: ASUS ThunderboltEX II Components: Computers & Accessories

Great info guys thanks. Will look into AKiTiO. Not sure how easy it'll be to get it shipped to Canada, but that's nothing new.
