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 9080 XT |
|---|---|---|
| TDP | 290 W | 330 W |
| VRAM | 20 GB | 24 GB |
| Memory bus | 320 bit | 384 bit |
| CUDA / Stream cores | 7168 | 8192 |
| Ray tracing cores | 112 | 128 |
| 3DMark Time Spy | 25500 | 28500 |
Between the Radeon RX 9080 and Radeon RX 9080 XT, the Radeon RX 9080 comes out ahead in tdp, while the Radeon RX 9080 XT wins on vram / memory bus. Overall, the Radeon RX 9080 scores 74.9 and the Radeon RX 9080 XT scores 79 on our Mars Score.
Which should you buy?
The Radeon RX 9080 XT edges ahead on the Mars Score (74.9 vs 79), but the 4.1-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 care most about tdp. The biggest gaps in its favor are tdp. The single most decisive one: TDP — 40.00 W less. 290 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 vram, memory bus, cuda / stream cores, among others. The single most decisive one: VRAM — 20.00% more. 24 GB vs 20 GB.
Both ship with comparable dlss, 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: AMD - Radeon RX 9080 or AMD - Radeon RX 9080 XT?
AMD - Radeon RX 9080 XT leads the current Mars Score by 4.1 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.
