Do MacBook Pro compatible Thunderbolt external GPUs work with Boot Camp?

  • 1
    As a mathematician I would say the equation is underdetermined. As Apple supporter I would ask: which MacBook Pro and which eGPU? – klanomath Sep 24 '17 at 23:55

Yes, in general, external GPUs work with Boot Camp just fine.

In the specific case, you need to ensure that you have Windows drivers for your eGPU and that your enclosure is supported by Boot Camp. Mostly this is not a problem in practice.

Note that it might require a bit of fiddling to get this working in some cases. For example note that it might not work if you plug in the eGPU on the left-hand-side Thunderbolt ports on the MBP, but work perfectly fine on when plugged in to the right-hand-side Thunderbolt ports (or vice versa).

You can find a list of user guides for setting this up with various GPUs and enclosures: eGPU.io - User Implementation Guides

Here's a nice guide that details some of the "fiddling" that may be necessary: eGPU.io - Boot Camp eGPU Setup Guide for Thunderbolt 3 MacBook Pro

  • Thanks a lot for your great answer, how about playing games in Windows through Bootcamp using an external GPU on Mac ? Anyone has feedback about this ? – MFJC Sep 25 '17 at 16:13
  • This is basically what a lot of these guides are about. It works fine. Please remember to mark as answered if this answers your question. – jksoegaard Sep 25 '17 at 18:15
  • Basically, if I understand correctly with your links, it works but it requires a substantial amount of tinkering at this point in time right ? – MFJC Oct 3 '17 at 9:39
  • Well, that is subjective ofcourse, but in my world it is only a very light amount of tinkering! – jksoegaard Oct 3 '17 at 13:21
