This bit of news could become rather interesting in the months and years ahead. 4Gamer, a Japanese gamer site, apparently got to interview David Wang, the Senior Vice President of Engineering for Radeon Technologies Group, and ask about support for DirectX Raytracing, or DXR. His answer was that AMD will continue to focus on accelerated ray tracing for offline CG production using Radeon ProRender, which has had support for accelerated ray tracing for years now, but support for ray tracing in games will wait until all product ranges, from low end to high end, can offer support.
Until that happens, this means NVIDIA will be the only source of DXR supporting GPUs, at least with its RTX line. I do not believe it has been stated if non-RTX GPUs will support DXR, which is able to utilize NVIDIA's RT cores but does not specifically require them, but that could further restrict the ability to use DXR and potentially also its deployment in games. AMD's commitment to waiting until the entire product stack can support DXR though also signals the company may not want to see the technology limited to the most powerful and most expensive graphics cards. Whether this means the upcoming Navi architecture, to be built on TSMCs 7 nm process will have support is unclear, as some speculate Navi might be intended to cover the entire product stack. Something else to wonder is how the next generation of consoles may be impacted, as currently AMD created the SOCs for both the Xbox One and PlayStation 4 families. We will just have to wait and see how things develops, but then we also need to wait to see DXR put to use as no games support it yet, Microsoft needs to release the Fall 2018 update for Windows 10 for support it as well.
