Now, @Kepler_L2 has shared some more information regarding these ray tracing enhancements coming to RDNA 4. These changes include the following:

• Double Ray Tracing Intersect Engine
• RT Instance Node Transform
• 64B RT Node
• Ray Tracing Tri-Pair Optimization
• Change flags encoded in barycentric to simplify the detection of procedural nodes
• BVH Footprint Improvement
• RT support for OBB and Instance Node Intersection

AMD has been on an uphill battle against NVIDIA who have been a generation ahead of them when it comes to ray tracing support. Although the first generation of ray tracing support came to AMD in 2020 with the debut of the RDNA 2 graphics family (Radeon RX 6000), NVIDIA was introduced back in 2018 with its Turing (GeForce RTX 20) lineup.

Despite launching a year after NVIDIA, the RDNA 2 GPUs lacked in front of the Turing GPUs and had an even more difficult time competing against the Ampere (GeForce RTX 30) lineup. With the current Ada (GeForce RTX 40) GPUs, NVIDIA is still miles ahead of AMD's latest Radeon RX 7000 (RDNA 4) lineup.

With these new changes coming to RDNA 4 GPUs, AMD might have a strong offering when it comes to Ray Tracing performance. Earlier rumors have also indicated that the Sony PS5 Pro will take full advantage of these Ray Tracing enhancements since the console market is
