Quick verdict

Between the GeForce RTX 5070 and Radeon RX 7900 XT, the GeForce RTX 5070 comes out ahead in tdp / cuda / stream cores, while the Radeon RX 7900 XT wins on ray tracing cores / vram. Overall, the GeForce RTX 5070 scores 63.9 and the Radeon RX 7900 XT scores 67.2 on our Mars Score.

Buying advice

Which should you buy?

The Radeon RX 7900 XT edges ahead on the Mars Score (63.9 vs 67.2), but the 3.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the GeForce RTX 5070 if you care most about tdp / cuda / stream cores. The biggest gaps in its favor are tdp, cuda / stream cores, boost clock, among others. The single most decisive one: TDP — 65.00 W less. 250 vs 315.

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. Its strongest claims are ray tracing cores, vram, memory bus, among others. The single most decisive one: Ray tracing cores — 75.00% more. 84 vs 48.

There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.

Decision guide

Which should you buy: NVIDIA - GeForce RTX 5070 or AMD - Radeon RX 7900 XT?

AMD - Radeon RX 7900 XT leads the current Mars Score by 3.3 points.The more useful decision is the trade-off behind that result: compare vram, cuda / stream cores, boost clock, tdp against the way you will actually use the product.

Choose NVIDIA - GeForce RTX 5070 if…

NVIDIA - GeForce RTX 5070 has the measurable edge on tdp w, cuda cores, boost clock mhz.

Choose AMD - Radeon RX 7900 XT if…
