AMD’s new RDNA 4 GPUs, expected to be released in 2024, can compete with NVIDIA with its brand new ray tracing technology.
AMDnew generation of RDNA 4 GPUIt is expected to be released in the second half of 2024, and it is predicted that this series will be able to compete with NVIDIA with the so-called “brand new” ray tracing technology.
AMD Can Reveal a Big Jump in Ray Tracing Performance with RDNA 4
AMD introduced hardware-accelerated ray tracing in 2020 with the Radeon RX 6000 series. However, these cards were inadequate in terms of ray tracing performance compared to NVIDIA’s RTX 30 series GPUs. Even though AMD achieved a significant performance increase with the RX 7000 series, it was still behind NVIDIA. New leaks show that AMD could gain a significant competitive advantage in ray tracing with its RDNA 4 GPUs. According to the statements made by @Kepler_L2, it is stated that RDNA 4’s ray tracing technology “RT looks brand new” and, unlike RDNA 3, “looks completely different”.
Architectural changes that AMD may have made to its RDNA 4 GPUs could play a critical role in improving ray tracing performance. In particular, BVH
Removing the Bounding Volume Hierarchy pass from BVH4 in favor of BVH8 for RDNA 4 is seen as a potential improvement that could improve performance.
According to claims by Moore’s Law Is Dead, the PS5 Pro will feature RDNA 4 RT technology and may have 2 to 4 times better RT performance than the vanilla PS5. If AMD really offered an RT solution with RDNA 4 that is completely different from previous architectures, these claims are likely to come true. However, since there is no definitive information yet about the actual ray tracing performance of RDNA 4, it is important to remember that this information is only rumor for now and may change.
* BVH is a technique used to reduce the load of ray tracing on the GPU; hence, the more effectively this technique is used, the faster ray tracing becomes.
