AMD’s FSR 4 upscaling is exclusive to 90-series Radeon GPUs, won’t work on other cards
1 min read
Summary
AMD will be releasing their new Radeon RX 90-series cards and RDNA4 architecture on March 5, alongside a new version of AMD’s FidelityFX Super Resolution upscaling technology, FSR4.
FSR and Nvidia’s Deep Learning Super Sampling are upscalers that take lower-resolution images and make them higher resolution, using AI to fill in the gaps between pixels to make the image look closer to native render quality.
FSR4 will be using hardware-backed machine-learning algorithms, using hardware newly added to RDNA4 and RX 90-series cards.
This is the same strategy that Nvidia has been using for its DLSS, utilising the tensor cores found in RTX GPUs to run machine-learning models to achieve superior image quality.
This means that FSR4 will not be compatible with GPUs that do not have the RDNA4 architecture.
