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..)
eGPU hardware: RTX 2070 AORUS Gaming box, the firmware is the full fat Thunderbolt firmware not the USB friendly one (i'll explain how I got around that) Cables used.
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.
Benchmarks
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.
