>the AMD 4700S only supplies one PCIe x16 expansion slot, which is restrained to a x4 signal. This means that the list of supported graphics cards is very limited as well. Worth noting (without further information) that "supported" does not necessarily mean "Only works with, and nothing else." There's nothing I see about this APU (be it the onboard GDDR6 or UMA of the APU) being inherently incompatible about a PCIe3 x4 (electrical) slot that only limits it to working with cited cards. Assuming you can still get drivers supported on contemporary OS', that hardware is compatible with cards as old as the 2005 ATi X800 and Nvidia 7000 series GPU's, or as new as the 6900 XT and 3090's, to any (PCIe) cards in between. Granted, the newer high end cards will saturate the 4GBps link on this APU in heavier loads, and see restricted performance, but they'll still be perfectly functional. This is something that was often discussed in the eGPU community only having x4 PCIe lanes to work with, but you could still plug in 980's, 1080TI's, Vega 56's etc if you were so inclined, and they'd work fine, and would still outperform lesser cards, they just wouldn't quite perform to their fullest potential. TL;DR: "Supported" and "Compatible" are not the same thing, and is likely just AMD heading off potential complaints from people trying to put high end cards into this for a SFF build.
