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 7700 XT |
|---|---|---|
| CUDA / Stream cores | 6144 | 3456 |
| 3DMark Time Spy | 16800 | 14800 |
| Ray tracing cores | 48 | 54 |
| TDP | 250 W | 245 W |
| Boost clock | 2512 MHz | 2544 MHz |
| DLSS | true | false |
Between the GeForce RTX 5070 and Radeon RX 7700 XT, the GeForce RTX 5070 comes out ahead in cuda / stream cores / 3dmark time spy, while the Radeon RX 7700 XT wins on ray tracing cores / tdp. Overall, the GeForce RTX 5070 scores 63.9 and the Radeon RX 7700 XT scores 61.6 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (63.9 vs 61.6). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the GeForce RTX 5070 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are cuda / stream cores, 3dmark time spy, dlss. The single most decisive one: CUDA / Stream cores — 77.78% more. 6144 vs 3456.
Pick the Radeon RX 7700 XT if you care most about ray tracing cores / tdp. Its strongest claims are ray tracing cores, tdp, boost clock. The single most decisive one: Ray tracing cores — 12.50% more. 54 vs 48.
Both ship with comparable vram, memory bus, so those specs do not 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 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 7700 XT?
NVIDIA - GeForce RTX 5070 leads the current Mars Score by 2.3 points.The more useful decision is the trade-off behind that result: compare cuda / stream cores, boost clock, tdp against the way you will actually use the product.
