Hello, this build guide is a work in progress.
After lurking on this website and forum, I decided to go for the Aorus Gaming Box GTX 1080. I tried it with different ultraportables and am now using it with the DELL XPS 13 9370 (the chosen one). Feel free to ask me what you would like to know or have tested.

System specs

  • 2018 XPS 13 9370
  • 13.3" 4K IPS screen
  • Intel i5-8250u
  • 8 GB dualchannel RAM 1866MHz
  • Intel UHD 620
  • Windows 10 Home 1803

Installation steps

Installation is on one hand very simple once you installed all drivers. Most important is to install the sofware from gigabyte, then windows soon finds new hardware (the GPU) and starts downloading the drivers. I updated all drivers manually via NVidia's site. It all takes a few restarts and the it works great.
On the other hand: I find the AGB still a bit finnicky: sometimes it works right away, other times I have to enable the graphics card in de control panel. Also, when I plug a TB3 cable/peripheral into the laptop, sometimes the AGB software starts up. I also have the LED failure message, tried the copy the other LED software from aorus, but decided to wait till gigabyte fixes it with a new update. It is best to look from time to time on the website, because not always the sofware updates itself.
The USB ports on the AGB are not thrustworthy when you update the firmware. When the AGB becomes more stressed and warm, the connection gets lost. That's not good when you have your controllers plugged in.
I undervolt my processor which makes the turbos last longer and the laptop cooler.


Benchmarks

My AIDa64 & Cuda-Z bandwidth, Cuda-Z and HWinfo:

Aida Aorus GB 1080 GTX
CUDA Z Aorus GB 1080 GTX bandwidth
CUDA Z Aorus GB 1080 GTX
HWinfo Aorus GB 1080 GTX

Underneath you find a comparison between a Dell 7577 (1060 Qmax), HP Spectre 13 and Lenovo Yoga 920. I also had an AGB 1070 and have some benchmarks from this. Tested on internal screen (4K) and external screen (2560*1080/1920*1080).


Comments 

I think for me coming from a 15.6" laptop with a Radeon 8850 (Dell Latitude 3540) my gaming setup has improved. Gaming is great on the internal 4K screen with relative low worknoise. I'am aware that by doing this the framerate takes a big hit compared with using an external screen, but with the power of the GTX 1080 I don't mind. Playing racinggames with my sons on the wide external screen is also an improvement: I don't need the steam link, but just use a long HDMI cable. Perfect for a minimalist. Most of the time I don't need the AGB and thats when the portability of the XPS 13 comes in handy: writing film reviews in the train or just taking the laptop into the garden. The included bag from the AGB keeps the AGB safe and looks clean.


Future
In the future I plan on buying a longer active TB3 cable (2m). Steve from Own or Disown mentions something like this could solve the bottleneck of the AGB. In his comparison with a different EGPU, the other one has a better (active?) cable. I would like to test if a better/active cable also will result in better benchmarks.
I'm also planning on buying a new external screen. I tried a 3440*1440 IPS ultra wide screen but was not satisfied. I watch a lot of movies and the 21*9 ratio is great for that. So now I wish for a 5k ultrawide screen (like the LG 34WK95U-W).

Hi, recently posted a similar set up (9370 and 1080gtx AGB) - how are you finding the heat dissipation from the laptop when gaming? Do use the laptop in a docked set up wher piping to external or run with 2 screens up?

Thank you for your question! I have my laptop on a stand and only use one screen when playing (so: external or internal). I'm really surprised on how this little laptop handles the heat: I have no problems at all. I also have to try it with undervolting via XTU (-0.850 CPU and -0.550 GPU are stable for me), but the undervolts keep resetting every time I reboot.
BTW I saw that you have the 9370 with the 8850U, maybe that gets warmer? When looking at benchmarks I saw that the 8250U was sometimes better, so I got that one. My only wish was that they would have one with 16GB. Do you have any other benchmarks? I'm curious on how the CPU might make a difference. In my testing with other laptops with the 8850U, I found that how the laptop was setup was more important (lanes, CPU clocking etc).

Thanks for the reply!

To be honest I hadn’t considered temperature when making the purchase and got swept up with more speed! More memory! Higher res! Etc etc

I’m happy to run further benchmarks! The only reason I’ve completed the cuda-z because there was link to it on this site (I’m quite paranoid about downloading executables off the net hehe).

Hi, is 8GB of ram enough for gaming with this setup? Will it bottleneck the performance of the AGB GTX 1080? Thanks!

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

Well, it depends, it depends. When gaming I don't feel it holding back the AGb 1080, but I think it will depend on the sort of game you play. You can find on youtube comparisons between different amounts of RAM, they mostly say that 8 GB would be fine. But I think that in the future, games will use more RAM. All said and done: I think I have enough RAM for my gamingneeds. Teh only think that came in my mind when choosing between 8 or 16GB was the higher clockrates of the 16GB, but the better performance of the 8250 vs the 8550 made me decide for the 8GB version of the XPS13. Hope this helps.

Thanks for the reply, were there any instances where you felt like there wasn't enough ram? If so, which game were you playing?

No, I haven't had any games where I thought that the RAM was the bottleneck. But when I encounter one I will report back. In the information above you can find some of the games I tested.

Do you have the aida benchmarks for this setup? 

I tried today the dell 9370 with the gaming box rx580 and i got the attache so i would like to compare. Thanks. one of the benchmarks is with the caldigit active 2m cable the other two are the apple 0.8 (the half finished benchmark) and the other the gigabyte cable.

I will back with you with my aida results. From your results it seems that the 2m active cable won't give more bandwith. Luckily it also doesn't limit bandwith.
