AMD working on porting RDNA 4 upscaling to RDNA 3 graphics cards says rumor

AMD is hard at work right now porting its FSR 4 upscaling to its previous-gen RDNA 3 architecture according to the latest rumors, something we should expect later this year to better battle NVIDIA and its DLSS upscaling technology.

In his new video, leaker Moore's Law is Dead reports from an anonymous source at AMD: "I (AMD) was hoping to have more updates for you about efforts to port FSR to RDNA 3, but unfortunately the people I know working on it had nothing new to say last time I talked to them".

MLID's source continued: "The only thing I heard was 'we are taking our time to port FSR 4 to RDNA 3 because we realize how important it is that we get this right' ... so, hey at least that confirms they are doing it!"

AMD launched its new FSR 4 upscaling technology with its new Radeon RX 9070 series "RDNA 4" graphics cards, launching the new GPUs with FSR 4 inside of 30 games at launch, promising many more titles with FSR 4 support throughout 2025. If the rumors are true and FSR 4 arrives on RDNA 3, then we'll see many more millions of Radeon RX series GPU owners enjoying improved AI upscaling in their FSR 4-supported games.

If the rumors are true, we could hear a tease or official confirmation from AMD in a couple of weeks time at Computex 2025.
