AMD has announced that its FidelityFX Super Resolution 4 (FSR 4) technology will soon be available for older Radeon GPUs, a move that expands the accessibility of its advanced upscaling features. Initially, FSR 4 was limited to the Radeon RX 9000-series GPUs based on the RDNA4 architecture, which includes only a few models released thus far.
In a recent update, AMD’s Computing and Graphics SVP, Jack Huynh, confirmed that the rollout for older GPUs will commence in July, targeting those based on the RDNA3 and RDNA3.5 architectures. This includes the Radeon RX 7000 series and integrated GPUs like the Radeon 890M and Radeon 8060S. Furthermore, support for the RDNA2 architecture, which encompasses the Radeon RX 6000 series and integrated GPUs such as the Radeon 680M, is expected to follow in early 2027.
Technical Adaptations for Older Architectures
To enable FSR 4 on these older GPUs, AMD has adapted the technology to work with the INT8 hardware present in RDNA3 and RDNA2 chips, as opposed to the FP8 data format utilized by RDNA4. This adaptation may result in a performance trade-off, as the hardware capabilities differ significantly between architectures.
While specific performance metrics were not disclosed, it was noted that modders have previously achieved FSR 4 functionality on INT8-supporting GPUs, experiencing a performance drop of approximately 10 to 20 percent compared to FSR 3.1 on the same hardware. AMD’s official implementation may yield different results, but the company aims to enhance the experience for users with older graphics cards.
Compatibility and Future Prospects
Any games that support FSR 4 will also be compatible with FSR 4.1 on Radeon 7000-series cards. Users will likely need to install a driver update in July to access these new features. Additionally, games that currently support FSR 3.1 can be configured to utilize FSR 4 through the Radeon graphics driver.
While AMD’s FSR technology competes with Nvidia’s Deep Learning Super Sampling (DLSS), which has broader game support and established hardware acceleration, FSR 4’s introduction to older GPUs signifies AMD’s commitment to enhancing the gaming experience for a wider audience. However, FSR 4.1 may not achieve the same level of compatibility as its predecessors, even with the expanded hardware support.
