My question is about eGPU's, what to put in them, and how exactly they work (See below).
Basically, I gather (please correct me if I'm wrong) that there's going to be almost no benefit to hooking up even the most powerful eGPU to a Macbook Pro via Thunderbolt 2? (I have a 2014 for now - No TB3)
But that aside, I want to know about eGPU's in general. I was hoping it might be possible to skimp on internal graphics in both my upcoming laptop (genuine) and desktop (Hackintosh) - (both of which are coming this year hopefully).
But from what I am understanding, that might be a viable solution for the laptop, but a terrible idea for the desktop.
Does an eGPU compliment the existing graphics? Or bypass it?
Basically (correct me if I'm wrong)...
-
Assuming all other specs are equal, a Laptop with the base GPU and a Laptop with the best GPU will perform the same when hooked up to an eGPU. Is that right? And an eGPU is likely going to be quite a bit faster than internal laptop graphics (So there's a cost advantage to cheaping out there).
-
A Hackintosh with a cheap GPU when hooked up to an eGPU will use the card in the eGPU. But then, why not just build it with an amazing GPU to begin with?
So that brings me to my questions:
-
If I build a Hackintosh with say an RX 5700XT, and also build an eGPU with that graphics card, is there any way to get them to operate together? (ie. Not bypass the internal). (And does it have the be the exact same card?)
-
Can I build an eGPU (in the future) that could keep my laptop running like a champ in 4 or 5 years, that would also be able to be used on my aging Hackintosh? (ie. Plug it in, and give it a new lease on life). Or is even TB3 too big of a bottleneck?
-
How much of a loss in performance (if you can quantify it somehow) is there between putting a card into an eGPU vs directly into a machine?
