Personally I think they’re recent losses are probably a result of the fact that Nvidia is so dominant and Intel entered the market. It’s hard to compete against someone who’s got ~70% market share while a new guy shows up and manages to only steal from your slice. The advantage Nvidia has of being the world’s most valuable company has got to be near insurmountable for AMD at this point. Even if AMD had an outright better product there’s a, not so small amount of people, who would probably still buy Nvidia just to be on the winning team.
