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 9070 |
|---|---|---|
| Ray tracing cores | 32 | 56 |
| 3DMark Time Spy | 13500 | 16800 |
| Boost clock | 2900 MHz | 2520 MHz |
| CUDA / Stream cores | 4096 | 3584 |
| TDP | 225 W | 220 W |
Between the Arc B770 and Radeon RX 9070, the Arc B770 comes out ahead in boost clock / cuda / stream cores, while the Radeon RX 9070 wins on ray tracing cores / 3dmark time spy. Overall, the Arc B770 scores 64.2 and the Radeon RX 9070 scores 64.9 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (64.2 vs 64.9). 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 care most about boost clock / cuda / stream cores. The biggest gaps in its favor are boost clock, cuda / stream cores. The single most decisive one: Boost clock — 15.08% more. 2900 MHz vs 2520 MHz.
Pick the Radeon RX 9070 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, tdp. The single most decisive one: Ray tracing cores — 75.00% more. 56 vs 32.
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 B770 or AMD - Radeon RX 9070?
AMD - Radeon RX 9070 leads the current Mars Score by 0.7 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.
