AMD has officially confirmed that its advanced FSR 4 technology, initially announced in September 2024, will finally be available for the Radeon RX 7000 and RX 6000 Series GPUs. This comes nearly two years after the technology’s debut, which was initially slated exclusively for AMD’s upcoming RDNA 4-based Radeon RX 9000 GPUs, sparking significant player dissatisfaction.
This announcement follows reports that Valve had urged AMD to bring FSR 4 to older graphics architectures. For Valve, this is crucial for devices like the Steam Machine, which would benefit immensely from improved image quality and performance. This is particularly relevant for systems using RDNA 3.5 GPUs, which were previously considered incompatible with AMD FSR 4.
AMD FSR Upscaling 4.1 for Radeon RX 7000 in July 2026; RX 6000 by Early 2027
Jack Huynh, Head of Computing and Graphics at AMD, has revealed that the company is extending FSR 4 support to previous generations. The Radeon RX 7000 series, based on the RDNA 3 architecture, will receive support in July 2026. Subsequently, by early 2027, AMD plans to bring the technology to cards based on RDNA 2, which includes the Radeon RX 6000 series and potentially other devices featuring RDNA 2 GPUs.
AMD FSR 4.1 is more than just a minor update to FidelityFX Super Resolution. AMD has revamped its upscaling strategy under the “Redstone” umbrella, a suite of machine learning-driven technologies that includes FSR Upscaling, FSR Frame Generation, FSR Ray Regeneration, and FSR Radiance Caching. The company clarifies that what was previously known as FSR 4 is now branded as FSR Upscaling, distinguishing it from the other components of the Redstone family.
A significant achievement is AMD’s ability to adapt the model for RDNA 3. While RDNA 3 GPUs feature AI accelerators, they lack the optimized FP8 execution path found in RDNA 4. This technical distinction is key. Huynh explained that RDNA 4 was designed with FP8 AI acceleration in mind – a floating-point format optimized for machine learning models. For RDNA 3, AMD had to adapt and validate the model to function using integer-based computation, ensuring visual quality is maintained and the performance gains outweigh any latency increase.
AMD Worked Overtime to Adapt This Crucial Technology
While some players have expressed reservations about using upscaled resolutions or AI-generated frames, the current global situation, where hardware upgrades are less frequent, has increased the importance of these technologies. For instance, a hypothetical Steam Machine capable of running Cyberpunk 2077 at 4K High settings at 30 FPS could potentially achieve a smooth 60 FPS experience by enabling AMD FSR Upscaling 4.1 and frame generation. This significantly enhances the gaming experience.
To achieve this wider compatibility, AMD developed a more accessible version of its technology that allows FSR Upscaling 4.1 to function on hardware not originally equipped with the same AI capabilities as RDNA 4. This aligns with earlier observations when accidental FSR 4 code releases suggested AMD was working on an INT8 variant, a more suitable approach for expanding support to older GPUs. While its official release was uncertain at the time, AMD has now confirmed this backward compatibility for RDNA 3 and, later, RDNA 2.
For Radeon RX 7000 users, this means a significant technological upgrade without needing new hardware. AMD promises that FSR Upscaling 4.1 will deliver improved sharpness, better temporal stability, and reduced artifacts, particularly in fast-paced scenes. Huynh highlighted optimizations in memory usage, motion vector validation, and artifact reduction – all critical aspects of modern AI-based temporal upscaling techniques. Users with older RDNA 2 GPUs can anticipate similar benefits, though they will need to wait until early 2027.
Over 300 Games to Benefit from AMD FSR Upscaling 4.1
According to AMD, the RDNA 3 architecture’s support for FSR Upscaling 4.1 will enable Radeon RX 7000 GPU users to experience the technology in over 300 compatible games from its launch. Notable titles include Cyberpunk 2077, Battlefield 6, and Assassin’s Creed Shadows. AMD has listed numerous games that support its “Redstone” FSR technologies. Some titles feature native integration, while others can benefit from AMD Software updates if they already support FSR 3.1 or higher in DirectX 12.
The upcoming support for the AMD RDNA 2 architecture is particularly noteworthy. Radeon RX 6000 GPUs were released before AMD integrated dedicated AI accelerators into its consumer graphics cards. This presents a greater technical challenge compared to RDNA 3. Nevertheless, Huynh confirmed that RDNA 2 users will also receive FSR Upscaling 4.1 by early 2027. This could have significant implications not only for desktops but also for portable devices based on RDNA 2. This is a dual benefit for Valve; the Steam Machine could launch with AMD FSR Upscaling 4.1, and the Steam Deck could see a substantial improvement in quality and performance in early 2027.
Strategically, this move significantly strengthens AMD’s position against NVIDIA. For years, FSR’s advantage over DLSS was its broader compatibility, as FSR 1, FSR 2, and FSR 3 could function on a much wider range of GPUs. With FSR 4, AMD had initially narrowed this scope by limiting AI upscaling to RDNA 4. This expansion aims to reclaim that narrative: offering a modern, machine learning-based upscaling technology without abandoning users of previous generations. However, it took them two years to achieve this milestone.
