Radeon graphics cards from AMD with DX12 feature raytracing via Microsoft’s DXR, as the company confirmed. However, the GPU power may not be sufficient.
AMD’s Ryzen 3000 CPUs start in the middle of 2019. However, Intel’s opponent for this is Comet Lake and thus again a 14nm processor and not a 10nm Ice Lake.
AMD is updating its entire product range this year. Ryzen 3000, the chipset X570 with PCIe 4.0 and Radeon Navi will be released on July 7th.
