While the PS5 Pro GPU is mainly based on the RDNA 3 architecture, it will anticipate several ray tracing enhancements that won't be seen until next year in AMD's first RDNA 4 PC graphics cards, such as:
- 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
According to another leak, it may also include thread reordering to reduce data and execution divergence, similar to NVIDIA's Shader Execution Reordering (introduced with the Ada Lovelace architecture) and Intel Arc's Thread Sorting Unit.
