AMD RDNA 4 GPUs To Feature Enhanced Ray Tracing Architecture With Double RT Intersect Engine, Coming To Radeon RX 8000 & Sony PS5 Pro 1

AMD RDNA 4 GPUs are expected to feature a brand new and enhanced Ray Tracing engine for Radeon RX 8000 & Sony PS5 Pro.

Previously, it was reported that AMD's RDNA 4 GPUs would feature major changes within its Ray Tracing engine. These enhanced RT blocks were to be incorporated in GPUs that would go on to power Radeon RX 8000 graphics cards and Sony PS5 Pro, both of which are expected to debut in the coming year.

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 in a heated battle with the likes of Microsoft and Sony battling out for the best hardware performance & capabilities that each of their flagship offerings has to offer. Sony's PS5 console is going to use a custom RDNA GPU with elements of the RDNA 4 GPU such as BVH8 traversal while RDNA 2 and RDNA 3 GPUs currently only support BVH4 traversal.

As per the latest reports, AMD's RDNA 4 GPUs are expected to debut in early 2025 with the next-gen Radeon RX 8000 graphics cards. So far, we only know about two chips in the making, the Navi 48 and Navi 44, both of which have been identified on multiple occasions as GFX1201 & GFX1200. If the 2025 release dates are true, then it will be some time before AMD officially announces these GPUs to the market.
