I'm asking which that poster is talking about for their setup.

You fail to understand they are very much the same thing. Anyway the OP seem to have an AMD so that along with a connection over OCuLink resolves most of the issues.

There are a couple of miniPCs like Beelink and Khadas that break out a PCIe5 x8 socket for eGPUs this is perfect but of course the question is why, you may as well have a desktop, though in the OPs niche case, it would work exactly how he wants with no loss.

Beelinks will take any GPU whereas Khadas is proprietary but at least their eGPU is compatible with other machines via TB.

Yeah, there was some EPYC boards that allow you to directly breakout PCIe that way, glad to see it’s filtered down. Hopefully that becomes an openly documented standard now.

OCuLink appears more like a native PCI-e link to the OS without some of the driver mess of USB4/TB4 it makes a difference in compatibility.

Oculink is native PCIe, I break out a couple of those interfaces on my PC.

200 is a lot for a few hours a month. It’s like £10 per hour give or take.

I had to look this up as it sounded wrong, and it is, the limit is 100hrs a month, should be plenty for the casual gamer.

Thanks guys for your input.
Sounds like maybe I should keep what I have for now and re-visit this idea in a year or so, when prices cool down a bit.

Nvidia monthly package is fine, but I guess it would only work for games that are available through that platform. All other games I have on Steam and GOG would need to rely on iGPU.

One thing ill add, mini pcs just can't be beat in terms of overall low power wattage and heat and sheer size.

I got an GMKTEC K12 mini pc its very slick for low power usage, were talking 7-8 watts idle at wall when doing nothing in windows 11 desktop, average 2 x 4K displays running office duties/YT on 2nd screen barely 25-35 watts.

Oculink port also and USB 4, but ocu is better for external gpus, itx and + systems id imagine will always soak up more power and watts overall. Still if you are not worried about the odd 30-50 watts usage, nothing imo can beat the stability and ease of an proper PC for gaming and performance.
