Just leaving this here...
We all know that is not actually good for AMD from a sales perspective. But before I go on...
You know what the main problem is...? Comments like "you guys", I.e. assuming that because someone does not trash AMD on all fronts, they are pretty much automatically AMD fanboys. Look how many warriors immediately jump in to defend nVidia left and right.
And under those circumstances, you think that an actual conversation is taking place? There is no actual conversation. The confirmation bias is extremely strong from both sides, which means, that nobody actually listens, but is only prepared to give rebuttals rather than understand. And because one side is much much larger in numbers, they are inevitably more annoying and more prone to group think.
I normally don't bother explaining, because of the above. But, let me just offer a few other alternative reasons that people with AMD hardware keep them longer on average...
First thing's first... Maybe the ones that buy AMD are actually more aware and more understanding of hardware trends. I mean... Who do you think is more likely to buy AMD? Someone random gamer, or someone that is actually knowledgeable about hardware? We know nVidia is known everywhere and AMD really is not. So there's your answer.
And a few other reasons... Rather than AMD customers being less interested in new technology, maybe they simply are less impulsive to get the newest shiny toy because of their knowledge. Or maybe the cards actually age better where they don't have the urge to upgrade as quickly. Or maybe they simply dislike nVidia's exploitation of consumers and get AMD instead.
There are a lot of valid reasons that are shrugged off. But the reality is, that if nVidia and AMD do EXACTLY the same thing, AMD is the one that is punished more harshly for it, if nVidia is punished for it at all.
All you have to do is watch the video above, and more importantly, watch the dismissal of it without any actual arguments, evidence or sources.
