Previously it had been getting toasty to the touch when running anything more advanced than CivV.ġ0A 120W 12vDC 2.5/5mm power supply by Mini-Boxġ) Remove/relocate Thunder2 fan so the Gigabyte RX 460 will fit. As an added bonus shifting the load to the eGPU also allows my iMac to run much cooler. This has done an excellent job at making the previously unplayable playable for casual gaming. Unigine Valley Extreme-preset benchmarking shows an improvement of 241 -> External:908 / Internal:698. This build bumped my Geekbench OpenCL benchmark score up from 5,568->55,360 which puts my new build somewhere between the M380 and M390: a successful modernization upgrade.
Systems running earlier 10.12.x will use the AMD9500Controller instead of the AMD9510 and won't require the second restart. Just posting because I didn't see anyone else validating that, yes, eGPUs work with TB1 21.5' 6770m iMacs.
