Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Arc B770 | AMD - Radeon RX 9060 XT 16GB |
|---|---|---|
| CUDA / Stream cores | 4096 | 2048 |
| Memory bus | 256 bit | 128 bit |
| TDP | 225 W | 160 W |
| 3DMark Time Spy | 13500 | 12400 |
| Boost clock | 2900 MHz | 3130 MHz |
Between the Arc B770 and Radeon RX 9060 XT 16GB, the Arc B770 comes out ahead in cuda / stream cores / memory bus, while the Radeon RX 9060 XT 16GB wins on tdp / boost clock. Overall, the Arc B770 scores 64.2 and the Radeon RX 9060 XT 16GB scores 64.3 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (64.2 vs 64.3). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the Arc B770 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 cuda / stream cores, memory bus, 3dmark time spy. The single most decisive one: CUDA / Stream cores — 100.00% more. 4096 vs 2048.
Pick the Radeon RX 9060 XT 16GB if you care most about tdp / boost clock. Its strongest claims are tdp, boost clock. The single most decisive one: TDP — 65.00 W less. 160 vs 225.
Both ship with comparable vram, dlss, ray tracing cores, 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 B770 or AMD - Radeon RX 9060 XT 16GB?
AMD - Radeon RX 9060 XT 16GB leads the current Mars Score by 0.1 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.
