System:
2014 Mac mini
i7 Dual-core
16 GB Ram
Intel Iris
27" Dell 2560x1440 monitor
MacOS 11.1 (No boot camp)
eGPU:
Whats left of an Akitio Thunder 2, Sapphire Rx Vega 56 PULSE 8GB, everything wired to a Corsair CX550F RGB PSU. Its not pretty.
Installation:
Disabled SIP and Authenticated-Root, Booted into 11.1, ran purge-wrangler, rebooted with egpu hooked up, display attached to mac mini HDMI. Shutdown, rebooted with display hooked directly to egpu on HDMI. Up and running.
Benchmarks:
Games barley ran before. The intel iGPU is not for gaming. Elder Scrolls online ran at about 40fps with everything off @720p. Far Lone sails was crazy choppy.
With the eGPU hooked up, running ESO at 2048 with everything on High, getting 51-66 fps (60hz monitor) I feel there is some cpu bottlenecking, but it does run much better than expected for a dual-core. Very playable. Far: Lone Sails runs everything on high. The RGB PSU is cool somehow. It needs some cleanup and a case for eGPU. It's an older GPU, it does have some coil whine, but not intolerable. Fans don't spin too much on the Vega, it dumps a lot of heat out the top of it.
Thanks for this post! I wanted to give this a try. I'm stuck with a Late 2014 mac mini, but mine is a dual-core i5 processor. I think I will follow your instructions here to add a eGPU. But everywhere I look, there are no other eGPUs I could connect to it other than the RX Vega 56. But I can't find the RX Vega 56 available for purchase anywhere haha
To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
