A closer look at AMD's RDNA 4 and FSR 4 Upscaling

Serving tech enthusiasts for over 25 years.TechSpot means tech analysis and advice you can trust After our initial analysis of the Radeon RX 9000 series announcement yesterday and the potential performance implications, let's put pricing aside and focus on some of the other interesting aspects of RDNA 4. Based on AMD's performance claims, the RDNA 4 architecture is more optimized for higher resolutions than lower ones. While the Radeon 9070 XT is claimed to be 42% faster than the 7900 GRE at 4K Ultra settings, at 1440p, it is 38% faster. The relative uplift at 1440p is 3% lower than at 4K, which isn't a massive difference but is still worth noting. Of course, the biggest and most important feature announcement AMD has made alongside RDNA 4 is FSR 4, which introduces an ML-based upscaling solution. Currently, FSR 2.2 and FSR 3.1 upscaling are not competitive with DLSS 4, so for AMD to compete, FSR 4 needs to be a major step up. With an AI-based upscaling algorithm, AMD now has a muc ...
