AMD continues to withhold any official announcement on bringing INT8 FSR 4 to RDNA 3 or older Radeon GPUs, including the RX 7000 lineup. The company has repeatedly stated that it has no updates to share, leaving users without clarity on future support.
At present, FSR 4 is limited to RDNA 4-based Radeon RX 9000 series GPUs. According to AMD, the technology depends on advanced AI hardware features that only exist in RDNA 4, making backward compatibility a complex challenge.
Current AMD Position
- No confirmed plans for INT8 FSR 4 on RDNA 3 or earlier GPUs
- No public response to leaked or unofficial implementations
- No timeline or commitment for expanded support
Despite the silence, leaked and unreleased FSR SDK files suggest that an INT8 version of FSR 4 can technically function on RDNA 3 hardware. Enthusiasts have already demonstrated this by enabling the feature on unsupported GPUs, though without any official backing.
AMD representatives have acknowledged that adapting FSR 4 to older architectures is technically difficult. However, they have stopped short of confirming whether these challenges rule out future updates entirely.
FSR 4 Support Overview
| GPU Architecture | Official FSR 4 Support | INT8 Variant Status |
| RDNA 4 | Yes | Official |
| RDNA 3 | No | Unofficial leaks |
| Older RDNA | No | Experimental only |
For now, AMD maintains its silence, keeping INT8 FSR 4 firmly positioned as a next-generation feature tied to newer hardware.
