I have a MacBook pro 13 inch 2012 and wanted to get an egpu to boost my graphics. I believe there is a similar topic about this but I wanted to ask my own questions 

What eGPUs will work will with my mac(Thunderbolt 1)? Will it work with a razer core x or any other of razers eGPUs? Do the Graphics cards I put in it matter to the mac?

Which eGPUs are cheapest and will work ok with my mac?Do I just need to get a normal eGPU and a thunderbolt 1 cable?

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Hi! Yes, I have one and it works, you can read the build linked in my signature. You can use a thunderbolt 3 enclosure like the razer core x by connecting it with the apple tb3->2 adapter (specifically the apple one, not other brands) and any tb1 or 2 cable (tb1 and 2 cables are the same). For bootcamp windows (or linux) any gpu should work but for macos only specific cards have drivers so to ensure compatibility, you may want to stick with an AMD card from 2016 (rx 400's) or later.

TB1 is too slow when using an eGPU to drive the built-in display.

An external display could work okay.

You would need the  Purge-Wrangler script.

An AMD RX580 8GB card at $170 plus a Powercolor Gaming Station at $250 would be a lower priced combo with good performance.

@mini-i5, you say tb1 is not enough for the built-in display but the guy above you says its fine? can you explain or do you just not know?

 

@nu_ninja, thank you for the help im going to use it, but the guy under you says "TB1 is too slow when using an eGPU to drive the built-in display" is this only true for some cases or what? thanks

I does technically work. I use the internal display from time to time. The problem is you get hit with around a 50% performance decrease at least when using the internal display over TB1. So it's not ideal and you might not be able to break ~40fps at any resolution in some games just due to bandwidth and latency constraints, though it depends highly on the game and lots of other factors. For example, I don't have hard numbers but I seem to see way better internal display performance in Bioshock infinite when using bootcamp windows, rather than macOS or linux. All that said, the eGPU is still a big uplift from the intel HD 4000 even on the internal display, but it's a far bigger and better boost if you can find an external display to connect.
