With the GeForce RTX 50-series "Blackwell" generation, NVIDIA is introducing the new DLSS 4 technology. The most groundbreaking feature being introduced with DLSS 4 is multi-frame generation. The technology relies on generative AI to predict up to three frames ahead of a conventionally rendered frame, which in and of itself could be a result of super resolution. Since DLSS SR can effectively upscale 1 pixel into 4 (i.e. turn a 1080p render into 4K output), and DLSS 4 generates the following three frames, DLSS 4 effectively has a pixel generation factor of 1:15 (15 in every 16 pixels are generated outside the rendering pipeline). When it launches alongside the GeForce RTX 50-series later this month, over 75 game titles will be ready for DLSS 4. Multi-frame generation is a feature exclusive to "Blackwell."
 
So this new feature will only be available for Blackwell.
