EGPU gtx 1080 bandwidth limit using usb-c on new macbook pro

[Felipesalomao]

I plan have only 1 setup for desktop and notebook. Will use new macbook pro with high speed usb-c/thunderbolt 3 to connect it to egpu, macbook thunderbolt 3 support 40 gb/s bandwidth. I plan use gtx 1080, my goal for gpu is VR (for that will run Windows on macbook), I will buy htc vive. 

My main question is, it's possible use gtx 1080 on macbook through egpu using thunderbolt 3 and get full performance (usb-c/thunderbolt 3 by some way won't  limit gtx 1080 performance (bandwidth limit maybe)?

 

Setup would be:

Macbook Pro

EGPU that support thunderbolt 3 40gb/s bandwidth 

GTX 1080

USB-C Monitor

Henger dock (just dock macbook and I have theoricaliy full desktop power). 

 

If possible, you think I will get enough performance for HTC vive? 

 

Thanks

Theoretically you can use the GPU at full bandwidth. But I wouldn't bother using an external GPU with a MacBook, it's gonna be too much hassle.

I''ve seen videos of people trying to do this, and the macbooks don't support it and barely work with them at all.

I know that running mac its have too much problems. My goal is use mac os for daily use and use Windows (bootcamp) for gaming (vr htc vive) and video render. Theoricaliy it should work, as thunderbolt 3 bandwidth not have gap.. But in real life, someone already tried it? Would be perfect setup. Power when docked (and full desktop, keyboard, monitor, mouse, etc + external gpu) and portability when undocked, all using just one beautiful machine.. I think if macbook have i7 + good ssd, only big gap is gpu. I really would like to know if it would work, if could handle full VR like htc vive running Windows.

Will research about them. Do you know someone that tried this setup, macbook pro 2016 + external gpu through thunderbolt 3 + gtx 1080, what was result in gaming fps, vr, etc when run Windows (I know that egpu on Mac OS is a problem, will use mac os only for daily tasks..)

There is some benchmark or fps running 4k games on those setups available? Thanks
