AMD’s Navi reveal at E3 was lacking the one thing NVIDIA has been touting ever since the Turing RTX graphics cards came out, that’s right Ray-Tracing or simply RTX. Dr. Lisa Su compared the RX 5700 XT and the RX 5700 to the GeForce RTX 2070 and
AMD did, however, lay a roadmap of its “Ray Tracing Vision” according to which the present GCN and RDNA architectures will support “Radeon Rays” for creators and developers on the shader level using the software fallback option of
So basically from what I can tell, the present gen RX 5700 Navi graphics cards won’t have proper ray-tracing support, but instead, the next-gen RDNA GPUs will. This will come in the form of hardware accelerated ray-tracing for lighting effects such as reflections, shadows and AO (just like NVIDIA’s present implementation) while full-scene RTX is still quite far off. It’s nice to see AMD at least acknowledge the future of ray-tracing in the mainstream gaming market, even though it’s not planning to support it right off the bat.
