RDNA 4
AMD's fourth-generation GPU microarchitecture, which focuses on strengthening ray tracing and AI acceleration capabilities, providing the dedicated machine-learning hardware foundation for FSR 4.
Timeline (last 90 days)
FSR 4.1 originally debuted as an exclusive feature for graphics cards based on the RDNA 4 architecture.
RDNA 4 (the RX 9000 series) focused on strengthening ray tracing and AI acceleration capabilities, and for the first time provided dedicated machine learning hardware as the basis for FSR 4.
FSR 4.1 initially relied on RDNA 4's AI acceleration units to run its ML models, and bringing it down to RDNA 2 means AMD must switch to an inference path or hybrid approach with lower compute requirements.
The RX 6000 series lacks the dedicated AI acceleration units of RDNA 4, so whether FSR 4.1's machine learning models can run efficiently will directly affect image quality and performance.
