Hi, here is a quick review of my Setup:

System specs:

Dell XPS 13 9310 2in1

Intell 1165G7

Intel Iris Xe

Palit RTX 2060 Super dual (175W TDP)

Win 10

Cooler Master NotePal CMC3 (12€) cooling pad for the notebook.



eGPU hardware:

Sonnet Breakaway Box 550, Maxonar 2m TB3 Cable 40Gbps, no mods.



Hardware pictures: 



Nothing special, I'm not at home at the moment, my normal Setup is a little bit better, maybe I add pictures later.

I just have to plug in the eGPU and a USB hub and I have a normal desktop PC.

The two TB4 ports of the Dell XPS are very useful for this. (external SSD,...)



Installation steps:

Just plugged the box in and installed GeForce Experience for the Nvidia Driver. Restart. Done.

Had a few crashes at first, fixed it with setting the energy option of the card to maximum performance in the Nvidia Settings.

No crashes at all, hotplugging works without any issues most of the time (disconnect eGPU in Windows first).

Tested a GTX 760 4GB for fun, works without any changes perfectly too.




I did all the test on my external Display.

I Overclocked my Card: Core +145 , Memory + 950, this is stable, not a single crash in any game

The memory clock speed is at 7950mhz stable

The core clock is at 1950mhz most of the time.

does not get hotter than 75 degrees C at around 70% fan Speed) 


3dmark Time Spy:

The score is a little bit inconsistent, the average benchmark is around 7130


I don't know, why 3dmark isn't showing my Hardware, but the run is valid.


Heaven Benchmark:

The average score is around 3500.

This is my first Post on this Site, just wanted to share this Setup, because I bought it after reading a few Posts on this Website.

I'm very happy with the result. The 2060 Super scores 7-15% worse than in a normal PC. I think this isn't that bad, a version with more than 175W would be great, tried vBios flashing, but no other Bios was working, maybe you know one for this card.

Sorry for my bad English and if you have any questions (diffrent Benchmark, more info...) just ask me Smile

Thank you for your build. Your 1471MiB/s H2D CUDA-Z result is comparable to a 16Gbps-TB3 link due to a 2-lane TB3 link as shown at https://egpu.io/best-external-graphics-card-builds/#perf . There have been other Dell XPS 13 9310 getting full 4-lane 32Gbps-TB3 performance so worth investigating some points noted:

32Gbps-TB3: to achieve ~2254MiB/s H2D (Nvidia) or ~2550MB/s (AMD) requires the correct TB3 enclosure firmware, a 40Gbps TB3 cable , NO additional active TB3 enclosure ports and a x4 3.0 host PCIe port (not x4 2.0). U-CPU systems must be in OPI 4GT/s. Macbooks with Nvidia eGPUs must not boot using apple_set_os.efi. FYI: Intel throttles 32Gbps-TB3 to 22Gbps which benchmarks as 20.40Gbps (AMD) or 18.91Gbps (Nvidia) in the important H2D direction.

@nando4, thx, for those information, bought a new cable, now everything is fine, I updated all Benchmark, I have a little bit more performance now xD
