The gap changes with resolution.
Graphics card differences grow with resolution, because higher resolutions load the GPU harder.
| Resolution | Arc A750 | Arc B580 | Difference |
|---|---|---|---|
| 1080p | 60 | 53 | +13% |
| 1440p | 58 | 53 | +9% |
| 4K | 59 | 56 | +5% |

So which should you buy?
The Arc A750 is faster, but the Arc B580 is the better buy per dollar. Take the Arc A750 only if you want the extra headroom and the price gap doesn't bother you.

Common questions.
Straight answers on the Arc A750 versus the Arc B580.
Is the Arc A750 better than the Arc B580?
Yes, but by less than the spec sheet suggests. At 1440p the Arc A750 scores 58 against 53 for the Arc B580 — roughly 9% faster. It also costs about $40 more at MSRP, so the question is whether that gap is worth the money for your build.
Does the Arc A750 or Arc B580 bottleneck a Ryzen 5 9600X?
Paired with a Ryzen 5 9600X at 1440p, the Arc A750 build comes out 19% GPU-bound, and the Arc B580 build comes out 25% 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 B580 to the Arc A750?
Only if you are also lifting the rest of the build. The Arc A750 is about 9% 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 B580 purely for frames, check the pairing first.
Which is better value, the Arc A750 or the Arc B580?
On performance per dollar at MSRP, the Arc B580 wins. The Arc A750 lists at $289 for an index of 58, and the Arc B580 at $249 for 53.
