looking at 6:35, considering that intel's e-cores dont always get used in games (yet they count towards CPU utilization), its possible that the game is CPU limited and not bandwidth limited. Did you do any tests on this, like lowering the resolution to see if performance increased? Id love to know!

Yepp I did, not CPU limited. The 125H "only" is an i5, but it's not the limiting factor here.

eGPU even on TB3 is great, but not for gaming. It's awesome for video editing and AI tasks, you can run it even on $200 Thinkpad turnining it into ultimate workstation. Difference for example in Davinci Resolve on TB3 vs PCIexpress are minimal.

For the mini PC, what about the 1070ti in your PC? This way to see if the difference is as huge as with the 4070. Basically at what point there is the sweetspot for what GPU to use and not lose too much performance. I like USB 4, but I feel like an occulink or whatever USB5 will be, would be more worth it. Now, can we get one, closed too, for this price? :)

Good Video and good testing :) Only thing You should also consider ist testing on 1440p. Besides the bandwith limitation are lower resoultions more cpu bound while higher resolutions are using more the gpu. It's possible that You see a better performance with the RTX 4070 egpu closer to the desktop at 1440p.
