I find it unlikely that AMD would be able to release a proper peer competitor to nVidia's best any time soon. Prior to the Ryzen launch, AMD lived through some really lean years. They saved wherever they could, and their GPU department saw very little investment on development for a long period. Since then, they have recapitalized the department, and are probably designing a proper next gen GPU architecture to replace GCN. However, it takes ~4-5 years to get a completely new arch on the market, and they only got to start a few years ago. Vega and Navi are both still shoestring budget designs.
