Buying advice

Which should you buy?

The Radeon RX 7900 XT edges ahead on the Mars Score (66.7 vs 63.1), but the 3.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Radeon RX 7900 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.

Pick the Radeon RX 9070 if you care most about tdp and boost clock. Its strongest claims are tdp, boost clock.

Both ship with comparable dlss, so those specs don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
