The attention then turned to FSR 4, and a footnote in AMD's pre-brief presentation slide which said that FSR 4 will only be available to the RX 9070 series for supported games with FSR 3.1 already integrated. AMD said that FSR 4 uses a machine-learning based algorithm to reconstruct details in its super resolution component, and that RDNA 4 provides a significant uplift in MLops over the previous generations of RDNA, and so initially FSR 4 will be available on the RX 9000 series, but the company will assess specific SKUs from previous generations that it thinks are capable of the AI acceleration performance needed for FSR 4 SR algorithm to work without imposing a prohibitive performance or latency cost. FSR 4 will be a significant improvement not just in frame-rate at a given preset, but also image quality.
