looks like you not done enough research, but you claim to know an aweful lot for someone who is not a pc gamer.
AMD were not happy with how inefficient directx was, so they created mantle, but they have said repeated times it was to push the industry forward rather than expecting it to ever become mainstream.
But anyway continue to ignore anything that doesnt match your view, go out and just buy the damn thing so we can see how you go.
The problems AMD has is twofold really.
As already mentioned their drivers are horrific vs nvidia, so even if the cards are technically equal on a hardware level, the nvidia will outperform the amd in most games, its a bit like when comparing consoles to PC's, console games are optimised more for those platforms so PC's usually need more grunt to get comparable performance to a console, it is what it is.
So for horsepower efficiency you could sort of look at it like this. consoles > nvidia pc > amd pc
Be aware sometimes the gap between amd and nvidia can be huge, as is on gta5 and witcher3.
Then you got the problem of how popular the hardware is, when amd release a new tech such as fuji e.g. they are now only putting it on their highest end cards and the lower ones are just rebrands of older tech, this is important because it means consumers say screw this I am buying nvidia. Result nvidia has the marketshare. Game developers who do you think they will prioritise on game development? the one that has market share.
Most of the amd 300 series cards are rebrands of 200 series cards which themselves were rebrands. This is one reason I said to you in another thread to get a x90 series AMD card when you yourself were going to buy a low end amd card thinking you could game with it on 4k resolutions.
Regarding the youtubers yes they often recommend AMD for budget builds, thats the one area AMD compete in well.
Of course regarding noise a 3rd party AMD card may have superior cooling which is also quieter, but thats the same with nvidia. So a 3rd party AMD card might match a stock nvidia card for noise, but a 3rd party nvidia card would still likely beat it, but to be fair to a lot of gamers they dont care about the noise so it might not be relevant to you, I said that as well. Remember as well to consider what you putting the card in, amd's card run hot, airflow cools them down, a tight fitting steam box wont have good air flow.
Also I guess you forgotten that amd is pretty bad in linux as well.

If you call me dumb again tho, I leave you to it, go ahead and tell us how it works out, you certianly seem to be one of the very few people even interested in a steam box, I consider it to have a very small market.
