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 9060 |
|---|---|---|
| VRAM | 12 GB | 8 GB |
| Memory bus | 192 bit | 128 bit |
| TDP | 190 W | 140 W |
| CUDA / Stream cores | 2560 | 1792 |
| Ray tracing cores | 20 | 28 |
| 3DMark Time Spy | 9400 | 10800 |
Between the Arc B580 and Radeon RX 9060, the Arc B580 comes out ahead in vram / memory bus, while the Radeon RX 9060 wins on tdp / ray tracing cores. Overall, the Arc B580 scores 59.2 and the Radeon RX 9060 scores 59.7 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (59.2 vs 59.7). 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 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 vram, memory bus, cuda / stream cores. The single most decisive one: VRAM — 50.00% more. 12 GB vs 8 GB.
Pick the Radeon RX 9060 if you care most about tdp / ray tracing cores. Its strongest claims are tdp, ray tracing cores, 3dmark time spy, among others. The single most decisive one: TDP — 50.00 W less. 140 vs 190.
Both ship with comparable 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 9060?
AMD - Radeon RX 9060 leads the current Mars Score by 0.5 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.
