System specs

Dell XPS 13
Ultra HD display (3840)
16 Go RAM
1To SSD
Intel i7-8550U CPU @ 1.80GHz (1991MHz) x4
Intel UHD Graphics 620  1Go 
Windows 10

eGPU hardware
 

KFA2 GALAX SNPR 
NVIDIA GeForce GTX 1060 6GB
Thunderbolt 3 included cable (50cm)

Hardware pictures 

Installation steps 

Nothing special. Just plugged it and waited a long time for everything to be recognized. Finally I installed the latest NVIDIA drivers.

Benchmarks 

Benchmark on internal monitor for Uningine Heaven (after bug fixing firmwire for H2D has been applied). On an external monitor using the same resolution I have a gain and I can reach 101 FPS instead of 89.

Comments 

I am not a real gamer, but it felt so much better that I can only be very happy. Will modify the info in the fly while using it. First use was 4th of August 2018.
My other comments :
- The TB3 cable is short (50cm)
- Its is really quiet and is not hot even at full load.
- Really small (same dimensions of a PSU but a little less tall)
- Cannot power the laptop. I have a message indicating that not enough power from the laptop.
- The galax name (white letters on the black plastic rectangle) on the front panel as seen on the builder website, does not show anything on mine.

Thank you for sharing the very first build with a GALAX SNPR eGPU enclosure. I noticed the H2D speed showed 11XX MiB/s. Dell had confirmed the XPS 9370 has four PCIe lanes and OPI 4 GT/s. It's likely then the Thunderbolt firmware of the enclosure has H2D limit.

Hi, I am no expert so I cannot say more. If you have other tests I can run, I will be happy to try and provide that.
Only thing to keep in mind that I use the internal monitor so maybe there is something to look there as well if the performances are not up to specs.

I checked on other builds here and indeed the H2D is half compared to others. Could it be the included cable?
Also, I have a Dell Dock plugged as Well to handle my Keyboard, mouse etc, but it also has VGA/Displayport outputs. Maybe it is shared between both? Will have to try tonight without it to see if I have full bandwidth.

EDIT : So after I tried, the presence of the Dell Dock barely changes the bandwidth and I still have 1200 Mibs with the enclosure alone on the TB3 port. Not sure what to test next (besides the cable).

It could be the cable. Windows doesn't show Thunderbolt connection speeds for Thunderbolt devices like macOS does so it will be difficult to tell unless you find a cable or device that shows an improvement.

You can at least use HWiNFO to verify that the Thunderbolt 3 controller is 8GT/s and x4.

The Dell Dock shouldn't affect the H2D this much if it has no display connected to it. Even if it did, it shouldn't matter if it's connected to a different Thunderbolt 3 port.

@stephane_betzi The low H2D read is most likely due to the enclosure firmware. Take a look at these two resources.

Here are the HWiNFO results. Seems ok for the TB3 controller as I understand the results window. Maybe as stated before by itsage, the enclosure is bottlenecking somewhat.

Ok, now I understand the content of your first message. It is sadly a recurrent issue that will net be easily fixed. I will shoot an email to KFA2 support to see what they have to say. Who knows, one can have dreams Smile

Here are the HWiNFO results. Seems ok for the TB3 controller as I understand the results window.

It shows CPU and GPU information but not all the PCIe information. PCIe devices are connected in a tree structure. Each branch has a PCIe bridge. Different PCIe devices and bridges can run at different link speeds and widths. You need to check all the bridges starting from the root port, down to the Nvidia card to find the minimum speed. I think we just care about the root port that the Thunderbolt 3 controller is connected to (can ignore the Thunderbolt 3 bridges except the one at the top nearest the root port).

HWiNFO shows 2.5 GT/s for the Nvidia card because you don't have a graphics program running such as what GPU-Z shows when you click the ? button.
