Which should you buy?
The Radeon RX 9070 XT edges ahead on the Mars Score (59.6 vs 67.3), but the 7.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Radeon RX 7700 XT if you care most about tdp. The biggest gaps in its favor are tdp.
Pick the Radeon RX 9070 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, 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 9070 XT is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
