Between the Radeon RX 7700 XT and Radeon RX 7800 XT, the Radeon RX 7700 XT comes out ahead in tdp and boost clock, while the Radeon RX 7800 XT wins on vram and memory bus. Overall, the Radeon RX 7700 XT scores 59.6 and the Radeon RX 7800 XT scores 62.5 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (59.6 vs 62.5). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Radeon RX 7700 XT if you care most about tdp and boost clock. The biggest gaps in its favor are tdp, boost clock.
Pick the Radeon RX 7800 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: 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.
