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 XT |
|---|---|---|
| Ray tracing cores | 32 | 64 |
| TDP | 225 W | 304 W |
| 3DMark Time Spy | 13500 | 19200 |
| Boost clock | 2900 MHz | 2970 MHz |
Between the Arc B770 and Radeon RX 9070 XT, the Arc B770 comes out ahead in tdp, while the Radeon RX 9070 XT wins on ray tracing cores / 3dmark time spy. Overall, the Arc B770 scores 64.2 and the Radeon RX 9070 XT scores 67.8 on our Mars Score.
Which should you buy?
The Radeon RX 9070 XT edges ahead on the Mars Score (64.2 vs 67.8), but the 3.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Arc B770 if you care most about tdp. The biggest gaps in its favor are tdp. The single most decisive one: TDP — 79.00 W less. 225 vs 304.
Pick the Radeon RX 9070 XT 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, boost clock. The single most decisive one: Ray tracing cores — 100.00% more. 64 vs 32.
Both ship with comparable vram, cuda / stream cores, memory bus, 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 XT?
AMD - Radeon RX 9070 XT leads the current Mars Score by 3.6 points.The more useful decision is the trade-off behind that result: compare boost clock, tdp against the way you will actually use the product.
