Be hard to bankrupt AMD when their CPUs make them tons of money.
And for the time being, AMD offers the best CPU-iGPU combination. Intel is still lagging behind on GPU tech and NVidia has no x86 CPU -- even though the most important patents expire in two years, I don't think NVidia will make an x86 CPU without the more modern extensions that are still patented.
In one hand I want the Nvidia quasi monopoly to end.
NVidia has no monopoly in the PC space. Intel + AMD combined far outnumber NVidia GPUs overall, NVidia just has certain niche markets where they dominate with high profit margins but that's not what this story is about.
If we are talking gaming (which by no means is a niche market), nvidia absolutely dominates the GPU market. The steam survey reports a market share of 75% for nvidia gpus
For me and my workflow they deliver better drivers on Linux than nvidia and that's all I care about. If they can be less expensive than an AMD gpu as well then I'll probably get one
Pretty well I reckon. Intel is very proactive in upstreaming their graphics drivers. Just make sure you're on a recent kernel with up to date Mesa libraries. Their OpenGL drivers aren't very fast for gaming, but Zink on Vulkan apparently runs well according to Phoronix
