External GPU with a All-in-one PC?

[JoshGruner]

I currently use a Dell XPS One 2720. It is great for editing, processing, and rendering. But the only problem I have with it is that it has a very poor GPU. Because of its amount of Ram, storage, and having a I7 4770S, I don't want to buy a whole new PC just to play some games.. Instead, I was looking into purchasing a external graphics card. My question is, Would it work with my PC, and if so.. what is there needed to connect one of these so it will perform well on my PC.

You will need a thunderbolt port which will not be included by default on an older system with a 4th Gen CPU sadly.  It looks like it was an optional extra available with certain configs, and if its there it would be thunderbolt 2, which may not be enough bandwidth, you are limited to Two PCI-E 2x? or 3? lanes not sure which revision.

Your all-in-one would need a Thunderbolt 3 port to use an external GPU. The XPS 27 2720 does not have one, unfortunately.

So I'm guessing there is no such converter that would allow me a Thunderbolt 3 port?

Incorrect. TB2 systems can use TB3 eGPUs using adapters.

It's x2 3.0, which shouldn't be all that bad for a midrange GPU like a GTX 1060 or 1070.

It's equal to x4 2.0 or x8 1.1 in this graph.

Not in something like an All-in-One PC. In a desktop you'd be able to find a Thunderbolt 3 PCIe add-in card probably, but All-in-One's are basically laptop-in-a-box computers with a screen and ports all integrated into the motherboard. Unless you've got one of those modular MSI All-in-One PC's you're not going to have much luck adding Thunderbolt 3 to it.

If your 2720 has the Thunderbolt port (it was optional and not on all machines) you should be able to convert it to Thunderbolt 3 and use an eGPU dock.

[JoshGruner]

So it does have a Mini Display port Thunderbolt 1 + 2, so is there a way to convert that to Thunderbolt 3?

Just did google search. Adapter exist, should be no problem if you have the optional port

Appreciate it!

Look for the connector with a Harry Potter scar.
