AMD actually lost marketshare in 2022, down to less than 10% now while NVIDIA is over 85%. People are not buying AMD gpus, no matter how expensive nvidia ones are.

I got a top of the line intel+amd laptop in 2014, in 2015 a GPU driver was released that made the system crash when booting up, they never solved the issue so I was stuck on the same drivers forever but the laptop still runs just fine with the GPU disabled (runs too hot otherwise). All my friends that bought AMD around that time had similar problems.

When getting a new top of the line machine around 2018 there was no way I would risk it again, none of my friends did either nor could I recommend AMD stuff without this disclaimer so nobody that asked for my advice bought one either. I won't be upgrading any time soon (and I wouldn't have in 2018 if not for AMDs screwed up driver) but as much as I hear how AMD has improved I probably won't ever feel comfortable spending as much as a PC costs now to find out if they indeed have or not. I'd rather go for the trusty Intel+Nvidia combo that hasn't failed me once since 2004, in fact my parents still run my build from 2008 with a trusty 9500GT without any issues.

People who have the money and knowledge to build something nice but aren't willing to troubleshoot and tinker too much anymore (like me) most likely had some sort of issue during AMDs dark years and won't want to risk it, those with the money but no knowledge will ask someone like me for suggestions and end up getting intel+Nvidia for the same reasons.

Maybe those of you who are living through AMDs revival and still have the energy to try stuff out will see them eat away at Nvidia on the long run but us old geezers will only change our ways when the kids have taken up troubleshooting duties for the family lol.

EDIT: it was the same story 20 years ago. Benchmarkers and magazines praised Athlon 64 for beating Pentium 4 but a few years down the line when I was the maintenance guy for a company those things were the bane of my existence. Gave them a chance in 2014, more headaches. Not again.
