- AMD’s upcoming FSR Redstone update adds three major AI-driven technologies: neural radiance caching, ray regeneration, and AI frame generation.
- Neural radiance caching uses AI to improve path tracing performance by reusing ray data.
- AMD directly responds to Nvidia’s technologies, which is a strategic move to close the gap in AI-based raytracing upscaling and image quality.
We recently got our first glimpse of AMD’s major update to FSR 4, codenamed “Redstone.” Arriving in the second half of this year, the new version appears to be AMD’s attempt to catch up to its rival, finally.
FSR Redstone now includes three new features: AI-driven frame generation, ray regeneration, and neural radiance caching.
Why it matters: AMD Redstone could greatly improve gaming visuals and performance on AMD hardware, making it potentially competitive with Nvidia.
Let’s start with the neural radiance cache, an important feature for games with path tracing. The GPU stores a cache of rays and feeds those samples to an AI model, rather than tracking every ray for every pixel, a shortcut for path tracing with the help of AI.
The other two features are significantly more relevant to current games. What Nvidia refers to as ray reconstruction is AMD’s ray regeneration. Ray regeneration will use an AI-driven denoiser instead of the ray tracing denoiser that games currently use.
That said, expect a significant improvement in image quality if AMD can achieve what Nvidia has done with ray reconstruction. The last feature is AI-powered frame generation. While frame generation is already a feature of FSR 4, it is not implemented using machine learning.
The success of the RX 9070 and RX 9070 XT may have inspired AMD, or AMD may be implementing a significant strategy to catch up to Team Green. Either way, changes are changes. FSR has always been behind in the ongoing battle over upscaling and AI image improvement, and it looks like AMD finally has an answer.
