In short

Hello everybody. Here's my addition to the implementation guide.

A Thinkpad P51 combined with a Sonnet Breakaway box (350W) and an MSI GTX1080 Gaming X is a nice setup if you do 3d modelling / VR (Oculus Rift).

 

Longer version

I'm an architect. I mainly do 3d modelling in SketchUp, Unreal Engine and evaluate/present design options in VR (Oculus Rift).
I used to work on a 5 year old desktop system (i5 3570) combined with a MSI gtx1080 gaming X gfx card. I wanted my setup to be more portable to be able show the VR at my clients' location as well.

I tried a gamer laptop (MSI GS63VR 7RG) for a day but that one got very hot all the time (85 to 95 degrees and thus very loud). Instead I chose a Thinkpad (already using that line for 10 years) combined with an eGPU setup.

Using this setup in windows 10 is very easy. Start laptop -> connect TB3 cable -> first time; install TB drivers -> disable Quadro in device manager -> start Unreal / Oculus -> enjoy.

I like that the laptop stays relatively cool (gpu disabled = less heat). On normal load (using Rift to view projects and using the internal laptop screen) you barely hear the fans spin. When playing VR games or during benchmarks they are more loud but not annoying. Maybe placing the eGpu under the table (longer TB3 cable) could improve that a bit.

 

 Specs of the Thinkpad P51

  • Product ID : 20HHCTO1WW
  •  Intel Core i7-7700HQ-processor (6 MB cache, maximaal 3,80 GHz) - 4 core, 8 threads
  •   15.6 FHD(1920x1080) IPS Non-Touch
  •   16 GB DDR4 2400 MHz SODIMM
  •   NVIDIA Quadro M1200 4 GB GDDR5
  •   512 GB SSD PCIe TLC OPAL2 (added another 512 PCIe + 512 ssd)

 

eGPU

  • Sonnet Breakaway Box (350W)
  • MSI GeForce GTX 1080 GAMING X 8G

 

Results

 

Suggestions to improve performance are always welcome. Feel free to ask questions for additional benchmarks.

 

Edit 171111 - Performance gets slightly better (1% - could also be something else) if I apply this tip I read on this forum; open DeviceManager -> View -> DevicesByConnection -> disable the PCIe controller just above the dGpu (Quadro).

 Edit 171116 - Replaced the original 0,5m TB3 cable with a 2m cable from Caldigit (TB3 cable-active, 5Amp, 40Gb/s Usb-c) so the Sonnet is now under the desk (more space, less noise when on high load). Not a big drop in performance (Cudaz still around 2070-2130).

Business grade Thinkpad goodness shines with your eGPU implementation. Care to submit more pics of your notebook + eGPU to bring it all to life?
