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 |
|---|---|---|
| CUDA / Stream cores | 4096 | 1792 |
| VRAM | 16 GB | 8 GB |
| Memory bus | 256 bit | 128 bit |
| TDP | 225 W | 140 W |
| 3DMark Time Spy | 13500 | 10800 |
| Ray tracing cores | 32 | 28 |
Between the Arc B770 and Radeon RX 9060, the Arc B770 comes out ahead in cuda / stream cores / vram, while the Radeon RX 9060 wins on tdp / boost clock. Overall, the Arc B770 scores 64.2 and the Radeon RX 9060 scores 59.7 on our Mars Score.
Which should you buy?
The Arc B770 edges ahead on the Mars Score (64.2 vs 59.7), but the 4.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
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, vram, memory bus, among others. The single most decisive one: CUDA / Stream cores — 128.57% more. 4096 vs 1792.
Pick the Radeon RX 9060 if you care most about tdp / boost clock. Its strongest claims are tdp, boost clock. The single most decisive one: TDP — 85.00 W less. 140 vs 225.
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 B770 or AMD - Radeon RX 9060?
Intel - Arc B770 leads the current Mars Score by 4.5 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.
