Sometimes I play on my iMac with standard Vega 56 and got a chance to test how well eGPU with 2080Ti will work in Bootcamp.

What do I have:

Setup:

Just plug&play downloaded Nvidia drivers from the official website and that's it. Works great, boots with connected eGPU also plug&play works as well. Once get error 12, but after the restart, it has gone. So it may have some issues and instability but after the restart, everything works flawlessly.

Result:

Short answer: not worth it if you plan to use it with an internal display. But for external display difference is noticeable, so with eGPU, you definitely need to get a second monitor.

Long answer: some numbers from 3D Mark:

TimeSpy (only Graphics score):

  • 2080TI - 6392
  • 2080TI (external) - 12856
  • Vega56 - 5653

Firestrike (Graphics / Physics / Combined):

  • Vega56 - 18232 / 18619 / 5618
  • 2080TI - 12561 / 13654 / 6499
  • 2080TI (external) - 25512 / 17739 / 7148

Firestrike Ultra (Graphics / Physics / Combined):

  • Vega56 - 4437 / 18643 / 2050
  • 2080TI - 5985 / 13835 / 3726
  • 2080TI (external) - 7783 / 18652 / 4534

As you see if you're using internal display, it is better to stay with standard Vega56.

But if you're getting a second display - it is definitely starting to shine.

Hope these results will help somebody.

Thanks for the iMac Pro + Nvidia setup info.

Which build of 2004 are you running?

@soadap, hi, are you using the razer x core, or razer x core chroma with 2080ti?

because I just bought this combo ( razer X CORE + MSI 2080TI ) and I notice the power supply only have 2x 8pins , the (2080ti GPU) needs 2x 8pins + 6pins for this GPU to work.

I'm not 100 percent sure if this will work if I purchase an adaptor ( Y splitter 8pins to 2x 8pins).

 

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

So my variant of 2080TI requires only 2 x 8pins and I was fine with regular Razer Core X.

Probably you got some OC version, which requires additional power.

if this will work if I purchase an adaptor ( Y splitter 8pins to 2x 8pins).

So peak power consumption of 2080TI according to tests is 300W and Razer Core X has a 650W power supply (Chroma has 700W), also you plan to use it with iMac, not a laptop, so you don't need to charge it and the power supply will be working only for GPU.

So I would say according to numbers and common sense it should work.
