Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | NVIDIA - GeForce RTX 5070 | AMD - Radeon RX 9080 XT |
|---|---|---|
| Ray tracing cores | 48 | 128 |
| VRAM | 12 GB | 24 GB |
| Memory bus | 192 bit | 384 bit |
| TDP | 250 W | 330 W |
| 3DMark Time Spy | 16800 | 28500 |
| CUDA / Stream cores | 6144 | 8192 |
Between the GeForce RTX 5070 and Radeon RX 9080 XT, the GeForce RTX 5070 comes out ahead in tdp / dlss, while the Radeon RX 9080 XT wins on ray tracing cores / vram. Overall, the GeForce RTX 5070 scores 63.9 and the Radeon RX 9080 XT scores 79 on our Mars Score.
Which should you buy?
The Radeon RX 9080 XT is the clear pick on raw spec strength, leading by 15.1 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 5070 if you care most about tdp / dlss. The biggest gaps in its favor are tdp, dlss. The single most decisive one: TDP — 80.00 W less. 250 vs 330.
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. The single most decisive one: Ray tracing cores — 166.67% more. 128 vs 48.
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.
Which should you buy: NVIDIA - GeForce RTX 5070 or AMD - Radeon RX 9080 XT?
AMD - Radeon RX 9080 XT leads the current Mars Score by 15.1 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.
