The gaming community is abuzz with anticipation, but AMD remains tight-lipped about FSR 4 INT8 for Radeon RX 7000 GPUs. Despite the excitement, AMD has yet to provide any official word on this highly anticipated feature.
The official silence is deafening: AMD FSR 4, a cutting-edge technology, remains exclusive to RDNA 4 GPUs, at least according to official sources. HardwareUnboxed confirms that AMD has no new updates to share, leaving gamers and enthusiasts in the dark.
The situation is intriguing because AMD has previously demonstrated a functional FSR 4 implementation on non-RDNA 4 hardware. However, the company's documentation restricts FSR 4 to the latest Radeon RX 9000 series cards, with older GPUs falling back to FSR 3.1.5. This limitation is justified by AMD's claim that FSR 4 relies on hardware-accelerated FP8 Wave Matrix Multiply Accumulate, absent in earlier Radeon architectures.
But here's where it gets controversial: AMD accidentally leaked evidence of an alternative FSR 4 implementation. In August 2025, the company briefly released FSR 4 source code, only to retract it soon after. However, the leak spread, and review channels demonstrated that FSR4 INT8 could run on RDNA 3 and even RDNA 2 GPUs with slightly lower performance and image quality compared to RDNA 4.
This revelation puts AMD in a tricky position. The company must now address the community's demand for FSR 4 on older GPUs, especially as RX 9000 series prices soar. AMD's own notes indicate that the driver-level upgrade path has limitations, affecting the integration of FSR 3.1 in DirectX 12 games and leaving Vulkan titles unsupported.
And this is the part most people miss: AMD's silence on this matter is puzzling, especially since they've left the door open for a potential FSR4-Lite approach. The community is eager for answers, but AMD has yet to respond to inquiries about FSR4 support on RDNA 2 and RDNA 3 cards.
What do you think AMD should do? Should they release FSR 4 for older GPUs, or is there a valid reason for the current exclusivity? Share your thoughts in the comments below!
