AMD RDNA4 To Feature An Entirely Different Block For Ray Tracing

AMD's intentions for RDNA4 appear to be significant, particularly regarding advances in ray tracing hardware acceleration. While AMD's Radeon RX 7000 GPUs are competitive, they have historically lagged behind NVIDIA's ray tracing capabilities. However, indications suggest that this dynamic may change with next-generation GPU architectures.

According to insights from Kepler_L2, a source known for AMD-related leaks, the company is reportedly developing an all-new ray-tracing hardware acceleration block. Unlike RDNA3, which was simply an extension of RDNA2, AMD's RDNA4 is expected to introduce a separate block specifically for ray tracing.

It is important to highlight that rumors suggest that the PlayStation 5 Pro may integrate RDNA4 RT acceleration. As mentioned earlier, the PS5 Pro is expected to support BVH8 (8-level Bounding Volume Hierarchy) traversal shaders, while current RT code is limited to a 4-level hierarchy. This suggests that the AMD RDNA4 RT core can potentially double the throughput per cycle.

Unfortunately, AMD has reportedly scrapped its big Navi4 chip plans. Whatever the RDNA4 RT offers will be limited to mid-range to high-end models, leaving fans to wait for the RDNA5.
