AMD's FSR 4 Upscaling Requires a Brand-New GPU
RDNA 3 GPUs will not gain FSR 4 upscaling, though they may benefit from improved upscaling algorithms in the future.
AMD confirms that its FSR 4 upscaling technology is exclusive to RX 9000 Series GPUs. The first models in this GPU family—the RX 9070 and RX 9070 XT—are on available March 6th.
