The latest AMD cpus do have transcoding, but Amd transcode isn't very good and isn't very compatible with Linux.
You can pick up an Intel A310 single slot GPU for $100 and it has AV1 encode, which is something that the igpu QSV doesn't have. Works very well in my Epyc motherboard with 76 pcie lanes. I definitely recommend going with an ATX 1st gen Epyc cpu+motherboard if you want something that can do NVMe raid.
It's compatible just fine. But the quality... well, it's not the worst, but definitely not the best quality.
Politely, not the worst compared to what, exactly?
It's way worse than qsv, nvenc, x264 or x265 which are basically the only hardware or cpu options you're likely to run into doing plex transcoding.
QSV is a very good product, high-quality and efficient. It’s also very mature, lots of signage in large deployments. I’ve tried AMD’s AMF streaming and at lower bit-rates you get a lot more blocking. It’s fine but QSV has an edge.

Lower quality at any given bitrate was my experience too. For local stuff it didn't really matter: if I could do 3x the bitrate to get the same quality, then meh, who cares.
If you're streaming/doing shit over the internet/encoding for something like Youtube, though, it's uh, not a good tradeoff because you can't necessarily even make that tradeoff.
