Arc B770 vs RTX 3080: Which Should You Actually Buy?
A head-to-head comparison of the Arc B770 and the RTX 3080. Intel 16 GB GDDR6, ~260 W. Last updated 2026-05-06.
Arc B770 vs RTX 3080: the short version
Two strong options in the same gpu class, aimed at different buyers. Below is a clean side-by-side, the real performance gap, and a no-nonsense recommendation so you stop second-guessing and buy the one that fits your build and budget.
Side-by-side specs
| Spec | Arc B770 | RTX 3080 | | --- | --- | --- | | Vendor | Intel | NVIDIA | | Tier | ultra | ultra | | Released | 2025 | 2020 | | VRAM | 16 GB GDDR6 | 10 GB GDDR6X | | Board power | 260 W | 320 W |
Real-world performance (estimated)
Estimated average FPS from a tuned config — your CPU, resolution and settings shift these, but the gap between the two holds:
| Model | 1080P Low | 1080P Med | 1080P High | 2K Med | 4K Med | | --- | --- | --- | --- | --- | --- | | Arc B770 | ~207 | ~166 | ~129 | ~93 | ~45 | | RTX 3080 | ~232 | ~185 | ~145 | ~104 | ~50 |
Head-to-head: who wins what
- Performance: Arc B770 and RTX 3080 trade blows by workload. Arc B770 has the edge where its stronger 16 GB GDDR6 and 260 W of headroom matters; RTX 3080 wins the rest.
- Efficiency: Arc B770 draws less power and is easier to cool and power.
- Value: Same-class rivals shift price constantly — check current street pricing and let the cheaper one at your target resolution decide value.
- Our pick: Buy Arc B770 if you want the outright ceiling and can cool/power it. Buy RTX 3080 if you want lower power, lower cost, or a feature the other lacks. (Plan for ~320 W board power plus the rest of the system.)
