Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | AMD - Radeon RX 9080 | AMD - Radeon RX 9070 XT |
|---|---|---|
| CUDA / Stream cores | 7168 | 4096 |
| Ray tracing cores | 112 | 64 |
| 3DMark Time Spy | 25500 | 19200 |

| Memory bus | 320 bit | 256 bit |
| TDP | 290 W | 304 W |
Between the Radeon RX 9080 and Radeon RX 9070 XT, the Radeon RX 9080 comes out ahead in cuda / stream cores / ray tracing cores, while the Radeon RX 9070 XT wins on boost clock. Overall, the Radeon RX 9080 scores 74.9 and the Radeon RX 9070 XT scores 67.8 on our Mars Score.
Which should you buy?
The Radeon RX 9080 edges ahead on the Mars Score (74.9 vs 67.8), but the 7.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
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. 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 — 75.00% more. 7168 vs 4096.
Pick the Radeon RX 9070 XT if you care most about boost clock. Its strongest claims are boost clock. The single most decisive one: Boost clock — 0.68% more. 2970 MHz vs 2950 MHz.
Both ship with comparable dlss, so those specs do not separate the two — focus on the differences below.
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: AMD - Radeon RX 9080 or AMD - Radeon RX 9070 XT?
AMD - Radeon RX 9080 leads the current Mars Score by 7.1 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.
