Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Arc B580 | NVIDIA - GeForce RTX 5070 |
|---|---|---|
| CUDA / Stream cores | 2560 | 6144 |
| Ray tracing cores | 20 | 48 |
| 3DMark Time Spy | 9400 | 16800 |
| TDP | 190 W | 250 W |
| Boost clock | 2850 MHz | 2512 MHz |
| DLSS | false | true |
Between the Arc B580 and GeForce RTX 5070, the Arc B580 comes out ahead in tdp / boost clock, while the GeForce RTX 5070 wins on cuda / stream cores / ray tracing cores. Overall, the Arc B580 scores 59.2 and the GeForce RTX 5070 scores 63.9 on our Mars Score.
Which should you buy?
The GeForce RTX 5070 edges ahead on the Mars Score (59.2 vs 63.9), but the 4.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Arc B580 if you care most about tdp / boost clock. The biggest gaps in its favor are tdp, boost clock. The single most decisive one: TDP — 60.00 W less. 190 vs 250.
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. Its strongest claims are cuda / stream cores, ray tracing cores, 3dmark time spy, among others. The single most decisive one: CUDA / Stream cores — 140.00% more. 6144 vs 2560.
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: Intel - Arc B580 or NVIDIA - GeForce RTX 5070?
NVIDIA - GeForce RTX 5070 leads the current Mars Score by 4.7 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.
