System specs: Mac mini 2014, i7-4578U, Iris 5100, Vega56 8GB, OSX 10.13.4

 

eGPU hardware  XG Station Pro, Vega56, Apple Adpater TB3/TB1&2 50cm Apple TB1/2 Cable

 

Hardware pictures: 

Installation steps Install GPU in enclosure and install the 3.0.2 purge-wrangler, shutdown and connect it all up.

 

Benchmarks:

Unigine Heaven @1440 74.5fps @900 125.9fps
GeekBench OpenCL 144k
CineBench r15 75fps
Unigine Valley @1440 67.7fps

 

Comments It's a bit faster than 2012, especially at lower resolutions where the GPU is bottlenecked by CPU.

I was asked about the USB-C from eGPU, it works fine I get full speed to my Samsung T5 SSD 460MB/s both ways.

will test windows at the weekend

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

In windows it was more tricky to get working....

With eGPU connected there was no display in windows when booting it was OK if I plugged in afterwards.  So with rEFInd I can work around that to enable dGPU from boot.

There was device code 12 all the time if I disabled root port 5 then it was OK, but I did the dsdt patch and it works fine after that. Unigine Heaven @1440 83fps so a little faster.

The USB C port doesn't work in windows, there is power but the embedded USB is not detected by windows so when I plug a device in there nothing to see. I can see the parent downstream switch but windows can't detect below, I tried to add and remove the device but no luck with that.

I can't recommend windows so much as it's not fully functional.

What were your results with the Mac mini 2012, how much faster was the 2014?
