Between the GeForce RTX 5080 and Radeon RX 9080 XT, the GeForce RTX 5080 comes out ahead in cuda / stream cores and dlss, while the Radeon RX 9080 XT wins on ray tracing cores and vram. Overall, the GeForce RTX 5080 scores 71.9 and the Radeon RX 9080 XT scores 80.1 on our Mars Score.
Which should you buy?
The Radeon RX 9080 XT is the clear pick on raw spec strength, leading by 8.2 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the GeForce RTX 5080 if you care most about cuda / stream cores and dlss. The biggest gaps in its favor are cuda / stream cores, dlss.
Pick the Radeon RX 9080 XT if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are ray tracing cores, vram, memory bus, among others.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the Radeon RX 9080 XT is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
