AMD Announces FSR Redstone, Next-Gen Neural Upscaler with Ray Regeneration and Neural Radiance Cache

The exhibition Computex 2025 AMD company presented FSR Redstone — a major update to FidelityFX Super Resolution technology that will be released in the second half of 2025. The new stage of FSR development is based on machine learning, and includes three key components: Neural Radiance Cache, Ray Regeneration и ML-accelerated frame generation.

FSR Redstone will be a direct competitor to NVIDIA's DLSS 3.5 and RTX Video Super Resolution. The first feature, Neural Radiance Cache (NRC), is responsible for forecasting and caching indirect lighting based on the analysis of reflected rays. This will significantly increase the realism of global illumination, especially in scenes with dynamic lighting and complex geometry.

The second key technology is Ray Regenerationanalog Ray Reconstruction from NVIDIA. It uses trained neural networks for pixel restoration, which cannot be accurately calculated in real time. This helps reduce noise and artifacts in ray tracing, as well as increase productivity without loss of quality. AMD claims that the algorithm already shows excellent results in benchmarks and is ready for integration into games.

The third component is Machine learning frame generation, which complements existing FSR upscaling algorithms and provides more smooth and clear picture. Unlike previous versions of FSR, Redstone is based on neural network models, which allows us to reach a level of quality and rendering speed previously available only on GPU NVIDIA RTX.

It is important to note that At launch, Redstone will only be available for graphics cards with RDNA 4 architecture., including the Radeon RX 9060 and RX 9070. However, AMD is considering adapting certain features for RDNA 3 in the future, especially in the context of frame generation and neural network upscaling.
