AMD has officially released its latest graphics technology update, codenamed FSR "Redstone". Released in December 2025, this update marks a pivotal shift for the company, moving from traditional algorithmic rendering to fully AI-powered solutions specifically for the Radeon RX 9000 series (RDNA 4).
Key Technologies:
- FSR Upscaling (ML) & Frame Generation (ML): Utilizing neural networks to boost framerates and image clarity, directly challenging competitive AI scalers.
- FSR Ray Regeneration: An AI-driven denoiser that significantly improves ray tracing quality by "cleaning up" light rays in real-time.
- Radiance Caching: Optimizes lighting calculations for complex scenes.
Who is it for? While marketed to gamers, Redstone is a massive upgrade for professionals using Unreal Engine 5. The Ray Regeneration feature drastically speeds up viewport rendering for Virtual Production and Architectural Visualization. However, note that these features require the AI accelerators found only in the new RDNA 4 architecture and are not backward compatible with older GPUs.
Conclusion from HYPERPC:
"Redstone proves that AMD is ready to compete at the highest level of AI graphics. Whether you are a hardcore gamer demanding realistic lighting or a creator building worlds in UE5, the new hardware requirements are justified by the performance leap. At HYPERPC, we are ready to equip your next build with the cutting-edge power of the Radeon RX 9000 series."
