Mid - High end laptop users (i.e. those buying laptops with discrete graphics) care just as much as everyone else about brand. You don't spend your hard earned money on a laptop without researching what goes in it.
AMD's problem's are more then not having a competitive gpu. There is a massive brand preference for Nvidia, and a not undeserved feeling that AMD is the cheap option. Personally I wouldn't go near AMD in a laptop due to their drivers sucking. Optimus isn't perfect but it's far better then anything AMD have ever managed to produce. I like most laptop users care much more about my games reliably working, then about 10% performance here or there. Equally system builders don't want lots of support calls about broken AMD drivers.
AMD can change that perception but it's not going to happen overnight, and like most things will cost money - you get what you pay for - something I have little hope AMD will manage as even when AMD was a lot better off then they are now they failed to produce decent laptop drivers.
I specifically avoided amd on my laptop purchase. I have a high end gaming laptop as my first high-end rig and I went for the high end nvidia chip.
Good choice since amd was horrendous at the time in mobile, but still, to downplay the brand is ludicrous and I agree with you dribble.
Most people I know who pc game are nvidia only. They don't even really know much of anything about amd other than their cpus definitely suck, and their gpus probably suck too by association. And their loud and hot gpus while nvidia are quiet and cool with good driver support. That's the most I've seen people know...
Too many forum users live in a bubble where they think other people read reviews as much as we do.... Newsflash, they're playing games, not reading benchmark reviews of gpus/games.... That's a very small groups of people who do that, who then make recommendations to everyone else.
I can see a number of oems having very limited options for amd gpu laptops(if they have them) and nvidia still dominating. Because that's just how strong nvidia brand presence is and you need something more than pitching price/performance. It hasn't worked in the past it won't work now. You need the performance crown at this point t if your amd, or you need an aggressive marketing campaign to show gamers they're being screwed by nvidia. Otherwise, I can see amd holding onto apple, but everyone else will require more work. Apple is actually the easiest one to get for amd. Their customer base is loyal to Apple, if Apple used horse poop for gpus, Apple fans will defend it. If dell uses amd as their primary laptop gpu, people will switch go a laptop vendor that gives them the gpu they want
