GCN supported DX 12 which happened way beyond 7970 launch and supported it much better than Maxwell and even Pascal for that matter. Probably the best example in favor for AMD - not too many others. Nvidia tends to put a lot of money, effort and support for new features. While at times it turns out to be a power play that fails (PhysX, GameWorks, GSync). I like that Nvidia took the chance and pushed out RTX - very cool! Do not like the price tag that came with it and at present, at least for me, it is not enough improvement to bother with for the cost and performance hit. I don't know, will have to see what Nvidia does with Super.I would really, really not advise investing too much attention to 'features' on AMD cards. Going back through their lineage even to the first ATi GPUs, there is a long history of AMD / ATi introducing 'features' that do not get used until they make their way into DirectX and are supported by other vendors, and in a form that is not compatible with what is originally released. Navi could always buck the trend, but it's a strong trend.
