The sketchy stuff shows up in cheap components with slim margins (budget AIO watercoolers, budget hard drives, budget PSUs budget/no-name ebay video cards).
That market is basically just Nvidia (80%+ market share and still dominating in performance/features).
I'm typing this on a machine with a fairly powerfull AMD GPU. The market for Nvidia is basically just Nvidia, everyone keeps using their special APIs. Their cards are not significantly more powerful than what AMD offers and their drivers suck because they're constantly using them for anti-competitive crap.
It's over 80% of GPU the market.

AMD can't compete with Nvidia's high end. Especially with the new 30XX series, which crush the performance of Nvidia's 20XX series.

Their drivers have a lot of features that AMD doesn't, like G-Sync, DLSS, RTX and others.
