The $250 price seems a it low when compared to the $199 price point, however, normal rules or expectations don't apply when your marketshare is in the basement. AMD aiming mainly for margins at first is a poor strategy in my opinion. The CPU division is rocking, so no fear of low cashflow or profits going forward. They need a bigger presence in the gaming world ASAP.One thing I'd be pretty confident about is that the actual price will be as high as AMD can get away with - AMD are a company who badly need to make money and grow their margins. So if it's a $250 gpu then it's going to have $250 performance. If it's got 2080 performance it won't cost $250.
Anyone claiming otherwise is just stoking the AMD hype train based around the mythology that AMD somehow care about their users more then profits.
Also, I remember a rumor on 28nm where Nvidia had first call on wafers due to their bigger demand affecting AMD sales. Perhaps AMD aims to reverse this on early 7nm by fabbing all their CPUs & GPUs at TSMC. If Nvidia can't get enough to do a mainstream GPU soon, they'll have a clear advantage.
