Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Arc B570 | AMD - Radeon RX 7800 XT |
|---|---|---|
| Ray tracing cores | 18 | 60 |
| TDP | 150 W | 263 W |
| 3DMark Time Spy | 8800 | 16500 |
| CUDA / Stream cores | 2304 | 3840 |
| VRAM | 10 GB | 16 GB |
| Memory bus | 160 bit | 256 bit |
Between the Arc B570 and Radeon RX 7800 XT, the Arc B570 comes out ahead in tdp / boost clock, while the Radeon RX 7800 XT wins on ray tracing cores / 3dmark time spy. Overall, the Arc B570 scores 57.8 and the Radeon RX 7800 XT scores 63.9 on our Mars Score.
Which should you buy?
The Radeon RX 7800 XT edges ahead on the Mars Score (57.8 vs 63.9), but the 6.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Arc B570 if you care most about tdp / boost clock. The biggest gaps in its favor are tdp, boost clock. The single most decisive one: TDP — 113.00 W less. 150 vs 263.
Pick the Radeon RX 7800 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, cuda / stream cores, among others. The single most decisive one: Ray tracing cores — 233.33% more. 60 vs 18.
Both ship with comparable dlss, so those specs do not separate the two — focus on the differences below.
Bottom line: the Radeon RX 7800 XT 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 B570 or AMD - Radeon RX 7800 XT?
AMD - Radeon RX 7800 XT leads the current Mars Score by 6.1 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.
