2017 13" Dell XPS 13 9365 [7th,2C,Y] + GTX 1060 @ 16Gbps-TB3 (AORUS Gaming Box) + Win10 [jc2222] // Nicehash crypto mining system  

Thank you for your build guide.

With regards to your decreased H2D CUDA-Z result, @itsage found the XPS 9365 has a 4-lane TB3 controller here.  Then following the footnote here,  it looks like your result most closely match those seen here. Ie: a 20Gbps rather than 40Gbps TB3 cable is being used.

The CUDA-Z result is limited at the numbers you see due to OPI 2 GT/s in the XPS 9365.

@itsage , is 2GT/s OPI for the XPS 9365 confirmed from your testing?  If so, would you mind making a note here and we'll change all XPS 9365 builds to be 16Gbps-TB3.  We were only just uncovering OPI as a bandwidth factor when you did your XPS 9365 testing in Jul-2017.

Hi @nando4. I looked through my archived folders and found some CUDA-Z screen captures. I ran the XPS 9365 with three eGPU enclosure I had at the time: AKiTiO Node, Sonnet Breakaway 350, and Mantiz Venus. The Memory speed hovering right at 1,600MiB/s.

I'm very confident the XPS 9365 is running 2GT/s OPI. The XPS 9250 is configured very similar in that it has 2 Thunderbolt 3 ports running through a x4 PCIe connection. It too suffers from 2GT/s OPI. The CUDA-Z result in my build guide of the XPS 9250 is identical as what we're seeing here for XPS 9365.

It seems like the 9365 doesn't have 4GT/s based on the CUDA Z results which is unfortunate because it was one of the factors I chose the 9365 over other 2-in1s. For 2GT/s the numbers I am getting seem appropriate. There is still a major performance boost, which is nice.
