2016 15" HP Spectre x360 940MX + GTX1080Ti@16Gbps-TB3 (AKiTiO Node PRO) + Win10 [Omniptizator]
System specs: 2017 HP Spectre x360 15", Intel Core i7-7500U 2.7GHz, integrated Intel HD Graphics 620, dedicated GeForce 940MX, Win 10 Pro
eGPU hardware: Akitio Node PRO, Asus ROG STRIX GTX1080Ti
System didn't detect anything when I plugged eGPU into corner TB3 I use for charging usually, but external case was recognized automatically when I tried the other port. OS always used dGPU on internal display even if I turned it off, so after half a day of tinkering, I decided to get 2018 Spring Creators Update (1803). After all the setting changes and tweaks I tried to get the setup working, I'm not really sure that OS update did the trick, but now when dGPU is offline - all games run on eGPU.
All this was done to get a decent gaming setup on my computer, I mainly use for IDEs (so CPU, RAM and SSD were main points when choosing it). Standard gaming laptops at the moment were either too bulky and fancy for office use, or at $4k price, so I decided to get a "hotel" gaming setup and still have a "business looking" laptop. Previously I was able to run Deus Ex: Mankind Divided only on lowest settings and at 1920x1080 on 20FPS, now it runs at ~45FPS at ultra and 1920x1080 (either I'm missing something, or the game is not that optimized). Divinity: Original Sin 2 keeps 40-50FPS occasionally going down to 30 at ultra settings on 4k. I'm pretty happy with the result, considering I still can use GPU in my home desktop if I want to. I can't currently compare desktop performance to an eGPU one.
Judging by host to device table at Build Guides section, I have this configuration really wrong, my bandwidth is almost 2 times lower than it should be on TB3 connection Only 2 free PCIe lanes are free for TB3, so bandwidth is limited here, thx @nando4
UPD2: A bit more about setup experience. As it turned out - for games to run at eGPU it was needed to disable dGPU and then reboot laptop. Also, almost every icon disappears from taskbar after I close games at resolutions, other than 4k. My theory is they are somewhat "left" on eGPU screen or render (this may be a bunch of baloney), as I see nVidia tray icon with GPUs status disappear, though its service still runs.
Talking about AkiTio Node PRO, it was smaller, than I expected. It's close in width x length to my laptop and not so wide - depth-dimension speaking (about as 1080Ti is in width). Really convenient handle to carry it around to colleagues' rooms for LAN parties. To my mind, only Aorus could best this case, and only in terms of size. Really satisfied with this choice
Your bandwidth is at 16Gbps-TB3 levels because this notebook has a 2-lane TB3 controller. That's because the 7th gen U CPU has 12-PCIe lanes. 4 are for the dGPU, 4 for the PCIe SSD, 1 for wifi, leaving only 2 available for the TB3 controller.
By comparison, the 13" Spectre x360 has no dGPU and so has a 4-lane TB3 controller.
See a 32Gbps-TB3 versus 16Gbps-TB3 bandwidth comparison here.
Hey there, it has been a while since you have those set up. How's everything going? Are you satisfied with the set up? Both performance wise and user experience wise. Also, do you only use one Tb port for both video and charging or one for video and one for charging? I have the same laptop and are thinking about buying this enclosure for my extra 970. It will be awesome if I can hear some feedback from you! Thanks.
Hello, I just stumbled on this post as I'm looking to buy an eGPU. We have the same HP but I was thinking about buying the Aorus Gaming Box with the GTX 1080. Of course, you have a different card so I wouldn't expect you to know all the details but I have some general questions about using an eGPU with our Spectre.
How is the bottle-necking, do you think the performance is bearable or is there any way to try to improve the limited bandwidth available with our model?
Did you have any connection/compatibility issues now that you've used it more?
Finally, do you find adding an eGPU to be worth the money?
I really appreciate you taking the time to post all of this information on the forum and I look forward to your reply. I have about a month until I move back to the United States and since this technology isn't currently available in Ecuador I've got some time to think about it.
