Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | NVIDIA - GeForce RTX 5080 | AMD - Radeon RX 9080 |
|---|---|---|
| TDP | 360 W | 290 W |
| CUDA / Stream cores | 10752 | 7168 |
| Ray tracing cores | 84 | 112 |
| VRAM | 16 GB | 20 GB |
| Memory bus | 256 bit | 320 bit |
| Boost clock | 2617 MHz | 2950 MHz |
Between the GeForce RTX 5080 and Radeon RX 9080, the GeForce RTX 5080 comes out ahead in cuda / stream cores / dlss, while the Radeon RX 9080 wins on tdp / ray tracing cores. Overall, the GeForce RTX 5080 scores 71.4 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 (71.4 vs 74.9), but the 3.5-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 / dlss. The biggest gaps in its favor are cuda / stream cores, dlss. The single most decisive one: CUDA / Stream cores — 50.00% more. 10752 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 tdp, ray tracing cores, vram, among others. The single most decisive one: TDP — 70.00 W less. 290 vs 360.
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 says both are well-rounded; the differences are about trade-offs, not quality.
Which should you buy: NVIDIA - GeForce RTX 5080 or AMD - Radeon RX 9080?
AMD - Radeon RX 9080 leads the current Mars Score by 3.5 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.
