I compared my benchmark with some Desktop Benchmarks of GTX 1080 Ti and RTX 2080 Ti and there are some differences -only for the RTX 2080 Ti. My GTX 1080 Ti peformas almost as good as benchmark tests, while the RTX 2080 Ti is clearly worse than the desktop version.

What do you think why this is the case?

Thanks for posting the build. Great setup.

CPU performance seems to be much better on  (Your) 2018 MBP (15") (I7-7920HQ 4-core) vs (My) 2017 MBP (15") ( i7-8850 6-core) comparing CPU scores from Timespy benchmarks

     (3955)  vs  (5495)
      (2017)  vs  (2018)
(I7-7920HQ 4-core)  vs  ( i7-8850 6-core)

Also I've noted on my MBP thermals are much better at full CPU/eGPU load at around 75C, using dGPU used to be in the 90Cs. Do you see a similar stark temp reduction on the 2018 using the egpu?

@enky_bubu, the CPU Score in those 3DMark Tests vary a lot. I have added some (old) test with the GTX1080Ti and there is was only 4600. Perhaps the GPU plays a factor, I have to redo the tests soon.

Yes, actually before having the eGPU I had been doing all things with the dGPU and this brought the notebook to scream (fans). This is much better since having the eGPU. It was actually the main reason to get one, because the RP560X is not a bad gpu, you can do anything with it, if you lower the details, but for the cost of a lot of noise and heat.

@OliverB, on 1440p and 1080p TB3 egpu bottleneck is bigger than 4K, pretty similar with comparison between 2080ti vs 1080ti on desktop, 2080ti 4K take better performance % over other lower resolution when I’m not wrong. 1080ti is 2 years old gpu so in term optimization it’s also better. I think with driver optimization the FPS may go better and better, especially on game fps, game developers and nvidia works is on the way imo, like BFV, heard latest nvidia driver bumps almost 50% FPS on dxr (dx12 Ray Tracing) performance, idk on dx11 I’ll take a look later.
On 1080ti and rtx2080ti I was only taking 4K benchmarks, since it was my purpose on egpu setting that could not be done on my laptop dGPU. 1070 maxq dGPU on it can run pretty well 1440p with less stutter compared my eGPU setting, despite open world 100~fps, 60 FPS g sync is enough to me. I always take FPS comparison on notebookcheck, I didn’t check on all my games FPS but noticed Battlefront 2, SoTR has pretty similar performance on 4K highest egpu both 1080ti and 2080ti.

Sorry if you've already answered this.  Have you tried internal monitor acceleration?  I know you get less performance using the internal monitor but it could be a mobile gaming beast if you can.

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

Yes I have. I post here a screenshot from Forza Horizon 4 on the internal display. You have to consider that the resolution is higher, 2880x1800. With 51 FPS it is still playable.

@joi_kansai, On your request I made TimeSpy and FireStrike Tests with the RTX2080Ti. To be complete I finally found the time to make the test of TimeSpyExtreme and FireStriktUltra with my EVGA GTX1080Ti SC2 and I must say, the performance of RTX2080Ti is quite disillusioning, especially for this setup with TB3-eGpu:

  GTX 1080 Ti RTX 2080 Ti
Time Spy Extreme
TimeSpyExtreme GTX1080Ti
TimeSpyExtreme RTX
Fire Strike Ultra
FireStrukeUltra GTX1080Ti
FireStrikeUltra RTX

In those 4k Tests the Graphic Scores of the RTX 2080 Ti compared to GTX 1080 Ti are only better by about 10-20%.

@OliverB Thanks for your time doing that, I know now quite sure Blade 15 Thunderbolt architecture made somehow lower graphics performance than my previous Blade 14.
Blade 15 gtx 1080ti Zotac Mini 
Firestrike Timespy
Blade 14 gtx 1080ti Zotac Mini
Firestrike Timespy
Timespy is dx12 benchmark so on dx12 titles it should gain more % improvement.
Here is similar raw performance gpu with 1080ti,xc 2080 Gaming with Blade 15.
Since more titles dx12 are optimized it’ll come more improvement that will separate 1080ti and 2080ti bigger imo.

Great!  Is it just plug and play for Nvidia cards while in Windows 10?

It depends. Once your system is running correctl with your eGPU, you can disconnect and connect it as many times you want. Best doing it by software, there is this option for nVidia carts, see also this post:
https://egpu.io/forums/pc-setup/how-to-accelerate-your-display-with-exactly-three-clicks/

But, depending on your system and what you want (e.g. acceleration on the internal display) you may need a correct timed hot-plug during boot. And I can tell, this can be nasty endeavor. Different macBooks behave diffent in this matter.
