RX 6900 XT vs Arc A770
The RX 6900 XT is about 7% faster at 1440p. Whether that is worth it depends on the rest of your build.
The gap changes with resolution.
Graphics card differences grow with resolution, because higher resolutions load the GPU harder.
| Resolution | RX 6900 XT | Arc A770 | Difference |
|---|---|---|---|
| 1080p | 71 | 66 | +8% |
| 1440p | 73 | 68 | +7% |
| 4K | 75 | 72 | +4% |

Common questions.
Straight answers on the RX 6900 XT versus the Arc A770.
Is the RX 6900 XT better than the Arc A770?
Yes, but by less than the spec sheet suggests. At 1440p the RX 6900 XT scores 73 against 68 for the Arc A770 — roughly 7% faster. It also costs about $650 more at MSRP, so the question is whether that gap is worth the money for your build.
Does the RX 6900 XT or Arc A770 bottleneck a Ryzen 5 9600X?
Paired with a Ryzen 5 9600X at 1440p, the RX 6900 XT build comes out 6% GPU-bound, and the Arc A770 build comes out 10% GPU-bound. Being GPU-bound is the healthy outcome — it means the graphics card is the part working hardest.
Is it worth upgrading from the Arc A770 to the RX 6900 XT?
Only if you are also lifting the rest of the build. The RX 6900 XT is about 7% ahead at 1440p, and gaps like that shrink further at 4K where the GPU does more of the work. If you are upgrading from the Arc A770 purely for frames, check the pairing first.
Which is better value, the RX 6900 XT or the Arc A770?
On performance per dollar at MSRP, the Arc A770 wins. The RX 6900 XT lists at $999 for an index of 73, and the Arc A770 at $349 for 68.
