Although AMD managed to roll out a competitive product series with its Radeon RX 7000 graphics cards, it has been struggling to keep up with Nvidia when it comes to ray tracing support and performance. According to the latest rumor coming from Kepler_L2 over at Twitter, AMD is now working on a completely new Ray Tracing engine. AMD's RDNA 3 GPUs were using an improved RT engine from RDNA 2 architecture.
RT looks brand new 🤔

This rumor does make sense considering that the upcoming PlayStation 5 Pro console, which will come with a custom RDNA GPU, is expected to use BVH8 (8-level bounding volume hierarchy) traversal shaders, according to Videocardz.com. This suggests an RT engine taken from the RDNA 4 GPU, as the current RT code only supports a 4-level hierarchy. On the other hand, recent rumors suggested that AMD is going to mostly focus on the mid-range to high-end graphics card segment, while the enthusiast series will have to wait for RDNA 5 architecture.
AMD is expected to launch its RDNA 4-based graphics cards in the second half of the year, so we might hear more about them during Computex 2024 show.
