AMD RDNA4: A Leap Forward in Ray Tracing
5/02/2024
Let’s delve into the exciting world of AMD’s next-generation graphics architecture, specifically focusing on the RDNA4 and its revamped ray tracing capabilities.
AMD RDNA 4: A Leap Forward in Ray Tracing
Background
AMD has been making significant strides with its Radeon GPUs, but when it comes to ray tracing, NVIDIA has held a competitive edge. However, recent leaks suggest that AMD is about to change the game with its upcoming RDNA4 architecture.
What’s New in RDNA4?
-
Brand New Ray Tracing Hardware Acceleration Block: Unlike RDNA3, which was an incremental improvement over RDNA2, RDNA4 introduces a completely different ray tracing hardware acceleration block. This means that AMD has reimagined how ray tracing is handled at the hardware level, potentially allowing for more efficient and powerful ray tracing performance.
-
PlayStation 5 Pro Connection: The PlayStation 5 Pro, rumored to incorporate RDNA4 ray tracing acceleration, further hints at the significance of this update. The PS5 Pro is expected to handle BVH8 (8-level bounding volume hierarchy) traversal shaders, whereas the current RT code can only manage a 4-level hierarchy. This implies that the AMD RDNA4 RT core could theoretically double the throughput per cycle.
-
Mid-Range to High-End Models: Unfortunately, AMD has reportedly canceled its plans for big Navi4 chips. As a result, the RDNA4 RT features will likely be available in mid-range to high-end models, leaving enthusiasts eagerly awaiting RDNA5 for even more powerful offerings.
Conclusion
While we await official announcements from AMD, the prospect of a “brand new” ray tracing engine in RDNA4 is exciting. PC Gamers and content creators alike can look forward to improved ray tracing performance and more immersive experiences in the near future.
