930 What kind of performance can I expect from the NVIDIA Titan Xp (Pascal) with the eGFX Breakaway Box?Nov-06-17
931 Can I use a Sonnet eGFX Breakaway Box with Boot Camp?Dec-05-17
Neither Apple, nor Sonnet, nor NVIDIA, nor AMD currently supports eGPUs with Boot Camp. Having said that, here's what we know...

Only these Thunderbolt Macs support 64-bit Windows 10 under Boot Camp:
MacBook Pro (2012 and later)
MacBook Air (2012 and later)
iMac (2012 and later)
Mac mini (2012 and later)
Mac Pro (Late 2013)

The community has had some success with NVIDIA and AMD GPUs under Boot Camp. Without serious intervention, most iMacs and all Thunderbolt 3 Macs will fail with Error 12. Some Thunderbolt and Thunderbolt 2 Macs will support NVIDIA eGPU cards with no problems and some will fail with Error 12 (not enough resources).

Here are two user forums at, Solving Error 12, and 2017 13" Non Touch Bar MacBook Pro + RX 580@32Gbps-TB3 (Sonnet Breakaway Box) + Win10 that discuss how to solve Error 12 for Thunderbolt 3 MacBook Pros. These solutions are for expert users. Good luck!
