AMD’s “Redstone” FSR Promises Major Leap in AI-Powered Upscaling
Table of Contents
AMD is poised to unveil a significant evolution of its FidelityFX Super Resolution (FSR) technology, codenamed “Redstone,” on December 10. The new iteration, teased by AMD’s General Manager and Senior Vice President Jack Huynh on X, leverages cutting-edge artificial intelligence and machine learning to dramatically enhance image quality and performance, particularly in demanding ray-traced environments.
A company release confirms that Redstone builds upon the foundation of FSR 4, introducing features designed to close the gap with NVIDIA’s DLSS technology. The advancements signal AMD’s growing momentum in the competitive landscape of image upscaling solutions.
Neural Radiance Caching: Reducing Ray Tracing’s Performance Cost
At the heart of Redstone lies Neural Radiance Caching, an AI model that dynamically learns how light behaves within a scene. This allows the technology to predict indirect lighting with greater accuracy, substantially reducing the performance overhead traditionally associated with ray tracing. This innovation could make high-fidelity ray tracing more accessible to a wider range of gamers.
Ray Reconstruction and Advanced Image Generation
Redstone also incorporates advanced ray reconstruction capabilities, mirroring features found in NVIDIA’s DLSS 3.5. Utilizing a neural network, the technology intelligently regenerates pixels that would otherwise be rendered incorrectly, resulting in sharper reflections and more detailed visuals.
Furthermore, AMD is introducing a new image generation method powered by machine learning. Unlike NVIDIA’s focus on doubling frame rates, AMD appears to be prioritizing visual fidelity with its approach to frame generation, aiming for more authentic intermediate frames.
Radeon RX 9000 Exclusivity – For Now
AMD has confirmed that FSR Redstone will initially be exclusive to the Radeon RX 9000 series of graphics cards, based on the RDNA 4 architecture. While acknowledging the disappointment this may cause, the company has not ruled out the possibility of bringing certain features to older RDNA 3 GPUs at a later date.
“We are committed to exploring opportunities to expand the benefits of our technologies to a broader range of users,” a senior official stated.
The full scope of Redstone’s capabilities will be revealed during the December 10 presentation, promising a detailed look at how AMD intends to reshape the future of PC gaming visuals.
