| TDP | 330 W | 304 W |
Between the Radeon RX 9080 XT and Radeon RX 9070 XT, the Radeon RX 9080 XT comes out ahead in cuda / stream cores / ray tracing cores, while the Radeon RX 9070 XT wins on tdp. Overall, the Radeon RX 9080 XT scores 79 and the Radeon RX 9070 XT scores 67.8 on our Mars Score.
Which should you buy?
The Radeon RX 9080 XT is the clear pick on raw spec strength, leading by 11.2 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 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. The biggest gaps in its favor are cuda / stream cores, ray tracing cores, vram, among others. The single most decisive one: CUDA / Stream cores — 100.00% more. 8192 vs 4096.
Pick the Radeon RX 9070 XT if you care most about tdp. Its strongest claims are tdp. The single most decisive one: TDP — 26.00 W less. 304 vs 330.
Both ship with comparable dlss, so those specs do not separate the two — focus on the differences below.
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: AMD - Radeon RX 9080 XT or AMD - Radeon RX 9070 XT?
AMD - Radeon RX 9080 XT leads the current Mars Score by 11.2 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.
