Performance loss on 4k external monitor

I've read a lot the past few days and it seems like the performance loss on an external 4k Monitor is lower than on an 1080p monitor.

I currently have a MSI GS66 Stealth with I7 10th gen comet lake cpu and rtx 2060 dgpu from work. But the performance is not good enough for 4k gaming.

So because I already got the notebook I'm considering an eGPU with TB3 instead of a desktop PC. But only if the performance loss on an external 4k monitor is <10%. 

Can't really find any 4k Benchmarks


Thank you.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

MSI GS66 has 2 M.2 (PCIe) slots:

For best performance suggest a M.2 eGPU over TB3 per my sig.  Can even do your own performance testing by obtaining an ADT-Link R43SG-TB3, testing it in the TB3 port then and splitting it off into it's constituent TB3 NVME M.2 adapter and ADT-Link R43SG M.2 eGPU adapter and testing it as a M.2 eGPU.
