Between the Radeon RX 9070 and Radeon RX 9080, the Radeon RX 9070 comes out ahead in tdp, while the Radeon RX 9080 wins on cuda / stream cores and ray tracing cores. Overall, the Radeon RX 9070 scores 63.1 and the Radeon RX 9080 scores 75.1 on our Mars Score.
Which should you buy?
The Radeon RX 9080 is the clear pick on raw spec strength, leading by 12.0 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 9070 if you care most about tdp. The biggest gaps in its favor are tdp.
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 cuda / stream cores, ray tracing cores, 3dmark time spy, among others.
Both ship with comparable dlss, so those specs don't 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.
