The RTX 5080 outperforms the RX 9070 XT in ray tracing by 25-40% (per Tom's Hardware 1440p tests) and offers superior DLSS features, while the RX 9070 XT provides stronger value in pure rasterization at 1440p (AnandTech). The NVIDIA card wins on features and longevity but trails in raw value. This is a close call only if budget is the top priority.
