Between the GeForce RTX 5080 and Radeon RX 9080, the GeForce RTX 5080 comes out ahead in cuda / stream cores and dlss, while the Radeon RX 9080 wins on tdp and ray tracing cores. Overall, the GeForce RTX 5080 scores 71.9 and the Radeon RX 9080 scores 75.1 on our Mars Score.
Which should you buy?
The Radeon RX 9080 edges ahead on the Mars Score (71.9 vs 75.1), but the 3.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
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 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 tdp, ray tracing cores, vram, among others.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
