System specs: 2020 13" HP Elitebook 830 G7, Core i7 10810u, 64GB of Ram, 4TB SSD, 7560 5G LTE, 400nit screen (i hated the sureview model..)
1x the cable that came with the gigabyte box
Installation steps : No special setup, booted windows, plugged in eGPU, installed nvidia drivers and that's it. I left DMA protection on in the bios.
Comments: I play a lot of overwatch and warzone. Overwatch loves hitting the 400fps limit on low and around 180-200 on Ultra settings. (you will need a high boosting CPU to get high frame rates, overwatch doesn't care about thunderbolt bandwidth. Warzone on the other hand is very bandwidth heavy. Going from a thunderbolt 3 20gbps cable to a 40gbps cable netted around 20-30% increases in performance.
The CPU in this thing is beast, with some cooling mods and throttlestop mods, well you can see the result in that screenshot. I usually run PL1 at 40 watts and PL2 at 65w. My cinebench score is 2700 pre cooling mods so once I figure out how to undervolt, I'll run more benchmarks.
As far as my HUB you see there on the back of my monitor. I have my laptop plugged into the hub where all my USB, ethernet and sound go through and my eGPU is attached to the passthrough port. Doing it this way means I don't have to worry about USB drop outs when heavily stressing the thunderbolt lanes. It does affect cuda z scores. I get H2D 2600-2700 and D2H 2800 but with the dock, I get much lower, as shown above. BUT this doesn't seem to affect games at all.
Please let me know if you'd like me to run or test anything.
