AMD Officially Expands FSR 4 Support to Radeon RX 7000 and RX 6000 Series

AMD has confirmed plans to bring its FidelityFX Super Resolution 4 (FSR 4) technology to older Radeon graphics cards, specifically those based on RDNA 3 (RX 7000 series) and RDNA 2 (RX 6000 series) architectures. This move marks a significant shift from the previous exclusivity to the RX 9000 series, following a source code leak that enabled unofficial usage. The official rollout is expected in the coming months, delivering improved visuals and performance to a wider range of gamers. Below, we answer key questions about this development.

1. What is AMD's new announcement about FSR 4?

AMD has officially announced that it will bring FSR 4 upscaling technology to Radeon RX 7000-series (RDNA 3) and RX 6000-series (RDNA 2) graphics cards. Previously, FSR 4 was exclusive to the RX 9000 series. The announcement follows a source code leak that allowed enthusiasts to enable the feature unofficially on these older cards. AMD's official support ensures better optimization, stability, and performance tuning for a broader user base.

2. Which specific graphics card models will receive official FSR 4 support?

The official FSR 4 support will cover all Radeon RX 7000-series GPUs built on RDNA 3 architecture (e.g., RX 7600, RX 7900 XTX) and all Radeon RX 6000-series GPUs based on RDNA 2 architecture (e.g., RX 6600, RX 6900 XT). This includes both desktop and mobile variants where applicable. AMD has not yet listed specific exceptions, but all mainstream models within those families are expected to benefit. The feature will be delivered through driver updates rather than hardware changes, making it accessible to existing card owners.

3. How did the community access FSR 4 on these cards before the official announcement?

Earlier in 2024, a source code leak from AMD revealed portions of the FSR 4 implementation, which community developers reverse-engineered to create unofficial patches. These patches enabled FSR 4 on RDNA 3 and RDNA 2 cards by bypassing the hardware checks that limited the feature to RX 9000 series. While functional, the unofficial version lacked official testing and optimization, leading to potential instability or reduced image quality. AMD's official release will address these issues with proper driver integration and quality assurance.

4. Why was FSR 4 initially exclusive to the RX 9000 series?

AMD initially tailored FSR 4 for the RX 9000 series due to architectural enhancements in the RDNA 4 platform, such as improved AI accelerators and dedicated upscaling hardware. The company likely wanted to demonstrate the technology's full potential on its newest hardware first. However, after the source code leak and positive community feedback, AMD recognized the demand and feasibility of bringing FSR 4 to older architectures. The official decision also reflects AMD's strategy to enhance the value of its existing GPU lineup.

5. When can users expect the official FSR 4 update to arrive?

The official rollout of FSR 4 for Radeon RX 7000 and 6000 series is scheduled for the coming months, with a more precise timeline to be announced. AMD will likely release the update through its Adrenalin driver software, possibly as part of a future major driver version or a dedicated beta program. Users are advised to watch for official announcements from AMD or check for driver updates via the Radeon Settings app. The company has not specified an exact quarter but suggested a 2025 release window.

6. Will the performance and quality of FSR 4 be identical on older cards compared to RX 9000?

While AMD aims for parity in visual quality, FSR 4 performance on RDNA 3 and RDNA 2 cards may not perfectly match the RX 9000 series due to hardware differences. The RX 9000's dedicated upscaling hardware can offload processing more efficiently, potentially offering higher frame rates at the same quality settings. However, AMD is optimizing the software stack to minimize the gap, and early unofficial tests suggest the difference is marginal in many games. Users can expect a significant improvement over FSR 3, but absolute performance may vary depending on the title and resolution.
