Just wanted to share the early results of my experiment with adding a Thunderbolt 3 eGPU enclosure to my T570 laptop. I just got this up and running, but everything operates mostly as expected so far.
The only negative items so far are that my Ultradock does not have a Thunderbolt 3 port, so I must connect the TB3 cable directly to the laptop. Also, when cold booting with the laptop installed on the dock, the bitlocker password screen will not display on monitors attached to eGPU. The logon screen only displays on laptop screen (even when laptop is closed).
My configuration is as follows:
Lenovo T570 Thinkpad Laptop
Intel® Core™ i5-7300U CPU @ 2.60GHz
8.0 GB RAM
Intel HD Graphics 620
Machine Type Model: 20H9000PUS
Windows 10 (64-bit)
Akitio Node Enclosure
Nvidia GTX 970 with 3 ea 1920 x 1080 monitors attached
Installed updatedThunderbolt drivers (16.3)
Plugged in Akitio Node with GTX 970 installed
Installed Nvidia drivers
Updated Akitio Node firmware
OpenGL with internal Intel HD Graphics 620 = 31.80 fps
CPU with internal graphics = 290 cb
OpenGL with Akitio Node and GTX 970 eGPU = 98.4 fps
CPU with external graphics = 326 cb
Internal graphics = 9 FPS / Score 237
External graphics = 102 FPS / Score 2574
Now running 3 x 1920 by 1080 monitors on the GTX 970 plus the laptop display. I believe that I can now use a total of 6 displays (three attached to eGPU and three attached to laptop, but I have not tried that config yet...
