Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | NVIDIA - GeForce RTX 5070 | AMD - Radeon RX 9070 XT |
|---|---|---|
| TDP | 250 W | 304 W |
| CUDA / Stream cores | 6144 | 4096 |
| VRAM | 12 GB | 16 GB |
| Memory bus | 192 bit | 256 bit |
| Ray tracing cores | 48 | 64 |
| Boost clock | 2512 MHz | 2970 MHz |
Between the GeForce RTX 5070 and Radeon RX 9070 XT, the GeForce RTX 5070 comes out ahead in tdp / cuda / stream cores, while the Radeon RX 9070 XT wins on vram / memory bus. Overall, the GeForce RTX 5070 scores 63.9 and the Radeon RX 9070 XT scores 67.8 on our Mars Score.
Which should you buy?
The Radeon RX 9070 XT edges ahead on the Mars Score (63.9 vs 67.8), but the 3.9-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, dlss. The single most decisive one: TDP — 54.00 W less. 250 vs 304.
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 vram, memory bus, ray tracing cores, among others. The single most decisive one: VRAM — 33.33% more. 16 GB vs 12 GB.
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.
Which should you buy: NVIDIA - GeForce RTX 5070 or AMD - Radeon RX 9070 XT?
AMD - Radeon RX 9070 XT leads the current Mars Score by 3.9 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.
