At Computex, AMD unveiled the next evolution of its FidelityFX Super Resolution (FSR) technology with the introduction of FSR Redstone, a major update designed exclusively for its upcoming RDNA4 GPUs, such as the Radeon RX 9070 series. Building on the foundation laid by FSR 4, Redstone incorporates machine learning and advanced rendering techniques to significantly enhance gaming visuals and performance. Among its key features are Neural Radiance Caching, which predicts the behavior of indirect lighting in a scene to reduce the need for full path tracing; machine learning–accelerated Ray Regeneration, which simplifies ray-traced scenes in a manner similar to NVIDIA’s DLSS 3.5 and AI-driven Frame Generation, which boosts frame rates by generating new frames between rendered ones.
AMD emphasized that FSR Redstone will be a “game changer” for RDNA4 users, but notably did not announce support for older GPU architectures, confirming that the new features will be exclusive to RDNA4. While FSR Redstone is set to launch in the second half of 2025 with no specific release date yet, AMD continues to expand the reach of FSR 4, which is expected to be supported in 60 games by June 5. However, no updates were provided regarding FSR 4’s availability for GPUs released before RDNA3.
