> There are only two markets for AMD cards that I see: Hackintoshes (increasingly irrelevant with the shift to the new Apple Silicon and inevitable phase-out of Intel-supporting MacOS releases), Linux systems, and AMD fanboys. All pretty small markets.

You're forgetting two more, one of which is massive: consoles and high-performance embedded gaming systems (basically, the Steam Deck and other high-end handhelds). Consoles aren't going to be super profitable on a per-unit basis, but AMD is making the chips both Microsoft and Sony are using in their boxes, and they're selling a lot of those boxes (right now, about 36MM since they debuted a little under two years ago). Similarly, the Steam Deck is a pretty damn good first attempt at a cohesive handheld that runs PC titles, and I could see that extending past Valve and into a generalized marketplace (and the fact you can plug in a USB-C cable into a dock and get a real Linux desktop is really, really cool).
