Custom eGPU

[louij2]

Hi has anyone built their own custom eGPU?

 

I am planning one that will be able to interface with a macbook/laptop and a server.

Something like this in theory.

Why would you need an eGPU for a server unless it's like a 1U? There are a bunch of options out there, some will hook right up to your M.2 slot, that's one that you could DIY. As far as making a custom one that works via Type C, good luck.

That would introduce a ton of latency and bandwidth issues, going through an adapter. Plus that won't work, that's only USB 3.0 not thunderbolt. I could be wrong but it would need to be thunderbolt to send/receive graphical data.

I can swap the riser to a thunderbolt 3 riser easy. Then the issue is thunderbolt to pcie?!?!?

You're better off with one of those PCIe slots made so that laptops can run an E GPU of an NVME m.2 slot. Get a type C to NVME M.2 dongle, hook up the PCIe slot to the dongle and you ought to be good to go.

Actually this riser possibly has everything that I need?

Would this idea work with my server? With a NVME to PCIE x1 adapter in the server.

Interesting that you found that, you may be interested in watching Linus do it here.

TLDR: Latency/Low bandwidth mean you're gonna lose a lot of performance but it'll work.

Just make sure you're not using laptop-sized PCI-E connectors, there's a difference between Laptop 1x/4x and Desktop 1x/4x
