Didn’t like the tone of my last attempt to reply, so here’s a rundown from a hardware enthusiast perspective.
Single board computers with no thunderbolt cannot have an external GPU, and have soldered permanent processors
The U sku on that cpu denotes low voltage. That cpu will have much worse performance than you expect. Ghz numbers usually advertise boost clocks, not stable performance.
Even when an external GPU is an option, the memory bandwidth of thunderbolt is not sufficient to run most cards and will result in micro stuttering and overall reduced performance. Usually you lose ~30%-50% of your performance depending on the card.
To top all of this off, you cannot use the steam deck as a reasonable expectation for this class of hardware. The deck runs a custom APU with a beefier than normal GPU. You will not get that performance from the linked micro pc.
I see, that does make sense.
I actually recently realized that the Mini PC shown in the listing I posted is not the same Mini PC as the one I have, the one I have seems quite a bit more powerful and also does have Thunderbolt/USB 4.0 (never tried connecting an eGPU though), I've actually been using it to play games at higher settings that would otherwise struggle on the steam deck, yes it's not as good as something with a bigger and dedicated GPU but still really good. Though I realize this probably isn't typical of Mini PCs, at least not yet anyway.
