Between the GeForce RTX 4080 SUPER and Radeon RX 9080, the GeForce RTX 4080 SUPER comes out ahead in cuda / stream cores / dlss, while the Radeon RX 9080 wins on ray tracing cores / tdp. Overall, the GeForce RTX 4080 SUPER scores 69.7 and the Radeon RX 9080 scores 74.9 on our Mars Score.
Which should you buy?
The Radeon RX 9080 edges ahead on the Mars Score (69.7 vs 74.9), but the 5.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the GeForce RTX 4080 SUPER if you care most about cuda / stream cores / dlss. The biggest gaps in its favor are cuda / stream cores, dlss. The single most decisive one: CUDA / Stream cores — 42.86% more. 10240 vs 7168.
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 ray tracing cores, tdp, vram, among others. The single most decisive one: Ray tracing cores — 40.00% more. 112 vs 80.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the Radeon RX 9080 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
Which should you buy: NVIDIA - GeForce RTX 4080 SUPER or AMD - Radeon RX 9080?
AMD - Radeon RX 9080 leads the current Mars Score by 5.2 points.The more useful decision is the trade-off behind that result: compare vram, cuda / stream cores, boost clock, tdp against the way you will actually use the product.
