My new Spectre arrived this week and I have been using successfully with my DevilBox.
It is currently working a single cable solution when I am Gaming with the Internal card disabled it can use the 60W provided by the DevilBox. HP always warns me about using a non HP adapter
The setup was a bit weird, I had to keep uninstalling and reinstalling the thunderbolt and Nvidia drivers, then suddenly it worked.
Currently I have only tested MGS Phantom Pain - I could run it at 4k 45fps on the internal screen - it looked pretty amazing.Â
These are the new bandwidth benchmarks after updating the Devilbox firmware. From here:

Thanks for your help! Downgrading did the trick. New picture attached. Doesn't seems to be as big of a difference that other experienced, but it's higher. I'll test it with real world fps games sometime during the week.
As IÂ understand from @4chip's comments, HP had a certain number of PCIe lanes to work with and the addition of the MX150 dGPU means the TB3 controller was wired with 2-lanes. So this is a 16Gbps-TB3 eGPU implementation.
Hi just to make sure I read your message above correctly because I am considering buying the same egpu. Does the new HP Spectre x360 15” run at 4 lanes or 2 lanes? Can you please confirmÂ
To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

The Spectre X360 15" has 2 PCIe lanes for its Thunderbolt connection.
Thank you. So there is no difference between the two 15” Spectres even the new on with the 8th gen CPU and MX150 still runs at 2 lanes and not full 4 lanes? I am asking just to confirm becaue there are two  2017 versions of the 15” SpectreÂ

*ALL* 15" x360 Spectres to date have 2 lanes on the TB3 port, as all 15" models have dGPUs. The difference GPU-wise is that earlier models have the built-in NVidia 940M(X) and the newer ones a MX150. The lane assignment has not changed.
I don't expect this to change until Intel makes more PCIe lanes available for its U class processors (which hasn't changed across the Skylake/Kaby Lake/Kaby Lake Refresh).
As this post is now a year old, could you confirm that the HP Spectre 15ch000xx models still have only 2 lanes? HWiNFO64 seems to suggest different but I could be looking at it wrong.

That's the wrong port. Thunderbolt port should be Hot-Plug capable. That might be the nvme or dgpu.
