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 9070 XT |
|---|---|---|
| CUDA / Stream cores | 10752 | 4096 |
| TDP | 360 W | 304 W |
| Ray tracing cores | 84 | 64 |
| 3DMark Time Spy | 23800 | 19200 |
| Boost clock | 2617 MHz | 2970 MHz |
| DLSS | true | false |
Between the GeForce RTX 5080 and Radeon RX 9070 XT, the GeForce RTX 5080 comes out ahead in cuda / stream cores / ray tracing cores, while the Radeon RX 9070 XT wins on tdp / boost clock. Overall, the GeForce RTX 5080 scores 71.4 and the Radeon RX 9070 XT scores 67.8 on our Mars Score.
Which should you buy?
The GeForce RTX 5080 edges ahead on the Mars Score (71.4 vs 67.8), but the 3.6-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 push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are cuda / stream cores, ray tracing cores, 3dmark time spy, among others. The single most decisive one: CUDA / Stream cores — 162.50% more. 10752 vs 4096.
Pick the Radeon RX 9070 XT if you care most about tdp / boost clock. Its strongest claims are tdp, boost clock. The single most decisive one: TDP — 56.00 W less. 304 vs 360.
Both ship with comparable vram, memory bus, so those specs do not separate the two — focus on the differences below.
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 9070 XT?
NVIDIA - GeForce RTX 5080 leads the current Mars Score by 3.6 points.The more useful decision is the trade-off behind that result: compare cuda / stream cores, boost clock, tdp against the way you will actually use the product.
