Arc B580 vs RX 6700 XT
The Arc B580 is about 6% 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 | Arc B580 | RX 6700 XT | Difference |
|---|---|---|---|
| 1080p | 53 | 51 | +4% |
| 1440p | 53 | 50 | +6% |
| 4K | 56 | 53 | +6% |

Common questions.
Straight answers on the Arc B580 versus the RX 6700 XT.
Is the Arc B580 better than the RX 6700 XT?
Yes, but by less than the spec sheet suggests. At 1440p the Arc B580 scores 53 against 50 for the RX 6700 XT — roughly 6% faster.
Does the Arc B580 or RX 6700 XT bottleneck a Ryzen 5 9600X?
Paired with a Ryzen 5 9600X at 1440p, the Arc B580 build comes out 25% GPU-bound, and the RX 6700 XT build comes out 29% 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 RX 6700 XT to the Arc B580?
Only if you are also lifting the rest of the build. The Arc B580 is about 6% 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 RX 6700 XT purely for frames, check the pairing first.
Which is better value, the Arc B580 or the RX 6700 XT?
On performance per dollar at MSRP, the Arc B580 wins. The Arc B580 lists at $249 for an index of 53, and the RX 6700 XT at $479 for 50.
