Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | NVIDIA - GeForce RTX 5070 Ti | AMD - Radeon RX 9080 |
|---|---|---|
| Ray tracing cores | 70 | 112 |
| 3DMark Time Spy | 20100 | 25500 |
| CUDA / Stream cores | 8960 | 7168 |
| VRAM | 16 GB | 20 GB |
| Memory bus | 256 bit | 320 bit |
| Boost clock | 2452 MHz | 2950 MHz |
Between the GeForce RTX 5070 Ti and Radeon RX 9080, the GeForce RTX 5070 Ti comes out ahead in cuda / stream cores / dlss, while the Radeon RX 9080 wins on ray tracing cores / 3dmark time spy. Overall, the GeForce RTX 5070 Ti scores 68.1 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 (68.1 vs 74.9), but the 6.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the GeForce RTX 5070 Ti 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 — 25.00% more. 8960 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, 3dmark time spy, vram, among others. The single most decisive one: Ray tracing cores — 60.00% more. 112 vs 70.
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 5070 Ti or AMD - Radeon RX 9080?
AMD - Radeon RX 9080 leads the current Mars Score by 6.8 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.
