AMD FSR 4 Debuts with AI-Powered Upscaling, Exclusive to RDNA 4 GPUs

AMD's latest upscaling technology promises significant visual improvements over FSR 3.1 but will require new Radeon RX 9000 series GPUs and game-specific support.

AMD demonstrated FSR 4, its AI-based upscaling technology, at CES 2025, showcasing improved image clarity, reduced ghosting, and fewer visual artifacts compared to FSR 3.1.
The technology was previewed on the upcoming Radeon RX 9070 and RX 9070 XT GPUs, which feature advanced ray tracing and AI hardware as part of the new RDNA 4 architecture.
FSR 4 requires RDNA 4 GPUs, making it exclusive to the Radeon RX 9000 series, and also depends on in-game support for implementation.
Side-by-side comparisons using Ratchet & Clank: Rift Apart highlighted sharper details, smoother transparency effects, and better handling of distant objects in Performance Mode.
AMD has not yet disclosed frame rate or performance metrics for FSR 4, and its adoption will depend on game developer integration and compatibility.
