AMD - Radeon RX 7800 XT vs AMD - Radeon RX 9070 XT

The Radeon RX 9070 XT edges ahead on the Mars Score (62.5 vs 67.3), but the 4.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Radeon RX 7800 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 boost clock, 3dmark time spy, cuda / stream cores, among others.

Both ship with comparable vram, memory bus, 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.
