FSR 4 for RDNA 3: Did AMD Accidentally Reveal Its Plans in an Official Presentation?

Attentive users spotted an intriguing detail in AMD’s presentation that could change our understanding of the compatibility of the latest FSR 4 upscaler. One of the official slides—demonstrating the HYPR-RX technology—shows the Adrenalin Edition utility with the FidelityFX Super Resolution 4 AI Upscale mode enabled, but on a Radeon RX 7800 XT from the RDNA 3 lineup. This discovery raises questions, especially since the company previously stated that FSR 4 would be available exclusively for RDNA 4 GPUs.

At CES 2025, AMD representatives hinted that adapting FSR 4 for RDNA 3 might theoretically be possible thanks to the presence of AI accelerators in its architecture, albeit with significantly less power than those found in RDNA 4. However, no official confirmation has been provided so far. The slide featuring the RX 7800 XT “running” FSR 4 has left the community wondering: is this simply a mistake, or a deliberate hint at upcoming surprises?

AMD’s Chief Architect for Gaming Solutions, Frank Azor, previously mentioned in an interview that engineers are exploring the possibility of porting FSR 4 to previous generations of GPUs. He stressed, “There are no guarantees—everything depends on optimizing the neural network models without sacrificing quality.” Experts believe that a simplified version of the algorithm, incorporating hybrid methods, might be necessary for RDNA 3 to compensate for its lower computational resources.

Expanding FSR 4 support to the RX 7000 series could be a strategic move by AMD to ramp up competition with NVIDIA’s DLSS. The more users who gain access to the technology, the more aggressively developers will integrate it into games. However, the key question remains: can the upscaler maintain image quality on older hardware? Analysts remind us that even with the current RDNA 4 version of FSR 4, quality depends on the game’s resolution, and optimizing for less powerful GPUs will require a delicate balance between performance and detail. For now, AMD remains silent, leaving ample room for theories. If the release of FSR 4 for RDNA 3 goes ahead, it could not only extend the lifespan of the RX 7000 series but also bolster customer loyalty.
