Over a year later, AMD is bringing improved FSR 4 upscaling to its older GPUs

"When AMD announced version 4 of its FidelityFX Super Resolution (FSR) graphics upscaling technology early last year, it came with strings attached: The improved hardware-backed image quality would be available only on Radeon RX 9000-series GPUs based on the RDNA4 architecture, not on any older Radeon GPUs."

"Over a year later, AMD Computing and Graphics SVP Jack Huynh has announced that a version of FSR 4 is finally coming to older GPUs. The rollout will begin in July with RDNA3- and 3.5-based GPUs, which include the Radeon RX 7000 series, as well as integrated GPUs like the Radeon 890M and Radeon 8060S."

"In "early 2027," support will also be extended to the RDNA2 architecture, which includes the Radeon RX 6000 series, integrated GPUs like the Radeon 680M, and the Steam Deck's GPU. This would also open the door to supporting FSR 4 on the PlayStation 5 and Xbox Series X and S, all of which also use RDNA2-based GPUs."

"Huynh's short video presentation didn't get into performance comparisons, but did mention that AMD had to work to get FSR 4's superior hardware-backed upscaling working on its older graphics architectures. RDNA4 includes AI accelerators that support the FP8 data format in the hardware, and porting FSR 4 to older GPUs meant getting it running on the integer-based INT8 hardware in the RDNA3 and RDNA2-based GPUs."

FSR 4 initially required Radeon RX 9000-series GPUs using the RDNA4 architecture. AMD has since released several 90-series cards, but not integrated GPUs for thin-and-light laptops or handheld devices. AMD Computing and Graphics SVP Jack Huynh announced FSR 4 support for older GPUs starting in July. The rollout will include RDNA3 and RDNA3.5 GPUs such as the Radeon RX 7000 series, plus integrated GPUs like Radeon 890M and Radeon 8060S. In early 2027, support will extend to RDNA2, including Radeon RX 6000 series, Radeon 680M, and the Steam Deck GPU. This may also enable FSR 4 on PlayStation 5 and Xbox Series X and S. Performance may be impacted because AMD adapted FSR 4 from RDNA4 FP8 AI accelerators to INT8 hardware on RDNA3 and RDNA2.
