Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Arc B570 | NVIDIA - GeForce RTX 5070 |
|---|---|---|
| CUDA / Stream cores | 2304 | 6144 |
| Ray tracing cores | 18 | 48 |
| TDP | 150 W | 250 W |
| 3DMark Time Spy | 8800 | 16800 |
| VRAM | 10 GB | 12 GB |
| Memory bus | 160 bit | 192 bit |
Between the Arc B570 and GeForce RTX 5070, the Arc B570 comes out ahead in tdp / boost clock, while the GeForce RTX 5070 wins on cuda / stream cores / ray tracing cores. Overall, the Arc B570 scores 57.8 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 (57.8 vs 63.9), but the 6.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Arc B570 if you care most about tdp / boost clock. The biggest gaps in its favor are tdp, boost clock. The single most decisive one: TDP — 100.00 W less. 150 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 — 166.67% more. 6144 vs 2304.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the GeForce RTX 5070 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
Which should you buy: Intel - Arc B570 or NVIDIA - GeForce RTX 5070?
NVIDIA - GeForce RTX 5070 leads the current Mars Score by 6.1 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.
