Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Arc B580 | AMD - Radeon RX 7700 XT |
|---|---|---|
| Ray tracing cores | 20 | 54 |
| 3DMark Time Spy | 9400 | 14800 |
| TDP | 190 W | 245 W |
| CUDA / Stream cores | 2560 | 3456 |
| Boost clock | 2850 MHz | 2544 MHz |
Between the Arc B580 and Radeon RX 7700 XT, the Arc B580 comes out ahead in tdp / boost clock, while the Radeon RX 7700 XT wins on ray tracing cores / 3dmark time spy. Overall, the Arc B580 scores 59.2 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 (59.2 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 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 — 55.00 W less. 190 vs 245.
Pick the Radeon RX 7700 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, 3dmark time spy, cuda / stream cores. The single most decisive one: Ray tracing cores — 170.00% more. 54 vs 20.
Both ship with comparable vram, memory bus, dlss, 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 AMD - Radeon RX 7700 XT?
AMD - Radeon RX 7700 XT leads the current Mars Score by 2.4 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.
