Hardware pictures
CPU uv -105.5 mV
Installation steps
Worked the Zotac into the Breakaway Box, connected DP-Cable from the 3070 to my monitor, connected TB3-cable from Laptop to Sonnet Box, installed latest Nvidia Driver, had to completely delete the existing driver, deactivated 2060 in Device Manager
System runs smoothly and silent after 2 days of trying (see comments below)
Benchmarks
Time Spy: eGPU 9550 (Graphics 10626, CPU 6081), "vanilla" no OC or UV (Lower scores after 2nd and 3rd tries. I don't know why), CPU uV: 9508 (see picture)
Userbenchmark: 131, 96, 111 (uV)

@largo_embargo, great setup. I’m thinking, maybe the cpu throttles after too many benchmark tests and that produce lower numbers in the gpu. My experience with sonnet has been very good too. Case is cool and quiet.

Thanks
I added the Futuremark Timespy Monitor. I cannot really judge, if the CPU shows unnormal throttling. Usermark gives a Throttling value of 84%. Again, cannot say if that high or regular, given the speed the 3070 puts on the system.
thanks for the post, great setup
can you please add some game performance comparision of dgpu rtx2060 and egpu rtx3070
To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
