Between the Radeon RX 7700 XT and Radeon RX 9070, the Radeon RX 7700 XT comes out ahead in boost clock, while the Radeon RX 9070 wins on vram and memory bus. Overall, the Radeon RX 7700 XT scores 59.6 and the Radeon RX 9070 scores 63.1 on our Mars Score.
Which should you buy?
The Radeon RX 9070 edges ahead on the Mars Score (59.6 vs 63.1), but the 3.5-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 boost clock. The biggest gaps in its favor are boost clock.
Pick the Radeon RX 9070 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, tdp, among others.
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.
