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 XT 16GB |
|---|---|---|
| Ray tracing cores | 20 | 32 |
| Memory bus | 192 bit | 128 bit |
| VRAM | 12 GB | 16 GB |
| 3DMark Time Spy | 9400 | 12400 |
| TDP | 190 W | 160 W |
| CUDA / Stream cores | 2560 | 2048 |
Between the Arc B580 and Radeon RX 9060 XT 16GB, the Arc B580 comes out ahead in memory bus / cuda / stream cores, while the Radeon RX 9060 XT 16GB wins on ray tracing cores / vram. Overall, the Arc B580 scores 59.2 and the Radeon RX 9060 XT 16GB scores 64.3 on our Mars Score.
Which should you buy?
The Radeon RX 9060 XT 16GB edges ahead on the Mars Score (59.2 vs 64.3), but the 5.1-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 memory bus / cuda / stream cores. The biggest gaps in its favor are memory bus, cuda / stream cores. The single most decisive one: Memory bus — 50.00% more. 192 bit vs 128 bit.
Pick the Radeon RX 9060 XT 16GB 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, vram, 3dmark time spy, among others. The single most decisive one: Ray tracing cores — 60.00% more. 32 vs 20.
Both ship with comparable dlss, so those specs do not separate the two — focus on the differences below.
Bottom line: the Radeon RX 9060 XT 16GB 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 B580 or AMD - Radeon RX 9060 XT 16GB?
AMD - Radeon RX 9060 XT 16GB leads the current Mars Score by 5.1 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.
