nando4>> Before seeking purchase help, please see these resources

 

1. How-To in the top menu for many common configuration steps.

 

2. Build Guides by users showcases system & eGPU capability & compatibility by way of users.  A valuable insight into the implementation complexity for your system using the same or similar intended eGPU hardware:

https://egpu.io/external-gpu-implementations-table/

 

3. The Buyer's Guide for enclosure offerings. Do take note of footnotes about criteria items:

https://egpu.io/external-gpu-buyers-guide-2018/

 


 

From what I’ve seen on these boards and other websites is that a lot of people with eGPU issues simply bought the wrong enclosure, the wrong card, or have an incompatible computer to begin with.

Investing $500-$1000, or even more, and only get headaches as your return simply sucks. The community here at eGPU.io is top notch and had direct influence on my success with getting my eGPU working, but I still had a fair amount of troubleshooting to do on my own.

So if you’re in the market for a setup be absolutely sure to consume this in its entirety:  https://egpu.io/external-gpu-buyers-guide-2017/

Anybody have any additional advice on taking your first steps for choosing the right eGPU setup?

The implementation table is a great way to get going, because replicating someone's setup is a lot easier than trying something nobody did before. A system with a lot of recorded successes is a better buy than one that is not.

I also advise people who are going for a gaming eGPU and DO NOT need OS X to not go and get a Macbook. Macbooks add a whole dimension of hurdles to jump or avoid in the eGPU context, and unless you have a good reason to get one (Being a longtime Mac user, or preferring OS X, or "I just want one" are all valid reasons, but people should know what they are getting into).

Ha ha! I am reading the forum for two weeks, and went through almost all implementation guides trying to figure out which use case is mine.

One thing to add:

When it comes to AMD vs NVIDIA, you should question yourself if native eGPU OSX support is a must or not

I started my eGPU endeavour about 1,5 years ago and did a lot of research myself. Yet I did not go with something that worked before, I was one of the first people to try the new AMD RX480 (in combination with the Akitio Thunder 2) to work under MacOS and Windows and an Macbook 15" 2015 with AMD dGPU onboard.

Of course it did not work out of the box, the whole Macbook 15" with dGPU was a pain in the ass for any eGPU setup back then. I've spend a good two weeks of debugging the issues together with @goalque. Eventually it worked in Windows, then it worked in MacOS shortly after, when AMD patched their MacOS drivers to incorporate a power issue fix in their kexts.

What I'm getting at is that you don't always have to go with what everyone else is doing, and you really need to bite yourself into this topic. With eGPU getting attention by all these major manufacturers, it is all a lot easier. Yes, a normal computer setup is easier to get to work. But for me having one system that has modular power is the best thing ever. My desk is clean and I don't need a big PC case.

I still use this AMD RX480 setup, now with an Mantiz Venus prototype board that I received about a year ago. Still with the Macbook 15" (2015) dGPU.

While true for experts and tinkerers, that isn't sage advice for most users. Most people who are asking about eGPUs just want an eGPU to just work. They do not want (and in some cases are not technically knowledgeable enough) to bite into the topic, or spend a long time hacking something to work, or risk money on something that might or might not work. Being a pioneer is great: Without people like you we would not be halfway where we are today, but it isn't for everyone, and part of what this community is about is making it easy/easier for the average Joe/Jane to get an eGPU setup working. Not because the average Jane is an idiot, but because their expertise in life lies in something else.

Yes you are absolutely right, and I did not want this to sound like only pioneers and tech-savy should use eGPU. But, especially back then, you'd buy an eGPU with the knowledge that you are 'hacking' the OS and that support is not always guaranteed. Even though someone has achieved it before, minor changes in your setup could ruin the whole device.

I think the advice here really sums it up! Some more things for mac users considering eGPU:

  • Search for forum posts and guides detailing your specific Mac model and find any specific issues or problems you might have based on the equipment you are buying. Sometimes implementation guides may not cover specific issues in detail - they don't need to. But you may encounter them, since usually a setup is not an exact replica (nearest ancestor/descendant Mac model, OS version, TB enclosure, GPU vendor, etc.).
  • Be mindful of what version of macOS you will be using, especially now that High Sierra w/ eGPU support is here.

 

When I joined the community (first foray into anything eGPU), there was no implementation guide for my Mac model (with discrete NVDA chip - 2014 15" MBP) with a TB3 enclosure and an NVIDIA eGPU. I then read about TB2 implementations elsewhere, but none with a TB3 enclosure. As with @FricoRico, I enjoy tinkering here and there so I took a chance anyway and discovered that it isn't possible to get my model to work on Windows in that configuration (a potential workaround is on this forum somewhere). Then, I tried switching out the eGPU for an RX 480, a first for this Mac model. That worked spectacularly. Now this model has problems on High Sierra, which I'm still trying to figure out - and this community has been a wonderful source for guidance and advice.

I'm new to the egpu thing, so I apologize if these questions have already been answered a billion times.

I have a 2017 5K iMac. If I connect a compatible AMD gpu via an Akito Node, does it to have a second monitor. And if it does require the 2nd monitor and I ran premiere on my iMac with my EGPU connected, and if I drag my premiere window onto the main imac display, will premiere still take advantage of the eGPU. Thanks in advance.

If any one can please help I have a mid 2015 macbook pro retina running bootcamp and I purchased a radeon rx 560 thinking that I could just connect it like a hard drive lol. Can someone please help me with a list of hardware I will need (Iam on a budget) to get this working or if I should just return the rx 560. I know I need an enclosure but I really dont want to buy the wrong one and I have no clue.

return it. High Sierra killed support for Thunderbolt 2 gpus. You have to have a 2016 or later MacBook Pro or 2017 or later iMac/iMac pro.

I have a late-13 mbp (retina) an I want to add an egpu to it runnig ino an external display

I'm thinking to buy aorus gaming box, the only problem is the I dont have TB3 in my computer...

I tried to look for an adapter, but could only find TB2 to TB3 (I need the other way around)...

do you know where can I find the right cable, and will it actually work good or TB2 will be too slow?

The Apple TB2 -> TB3 adaptor is bidirectional. It allows TB2 macs to use TB3 accessories like the AkiTio Node Pro. It also allow new TB3 Macs to use older TB2 accessories, like the OWC TB2 Docking station. All you need to use the adaptor is a regular TB2 cable and the adaptor. With those two you have male TB2 at one end and male TB3 at the other.
