Pair the Arc B580 with the Ryzen 7 7700X or the Core Ultra 5 250K Plus, or anything faster. By the figures any current processor keeps up with it, but Intel Arc cards lose more than NVIDIA and AMD cards with slower processors, because their driver needs more processor time.
Which current processors keep the Intel Arc B580 from waiting, in a typical game at high settings. Faster than a group needs gains nothing you can see at that resolution, so the useful choice is the least powerful processor in the group you play at. Listed fastest first; each links to the full result for the pair.
Older processors are a poor match for Intel Arc cards: many lack Resizable BAR, which Arc depends on, and the rest are slow enough that the Arc driver’s extra processor time costs more than the figures show. Check your own pair in the calculator, which warns where this applies.
Each processor and the Arc B580 are compared at each resolution with the same model and the same reference data as the bottleneck calculator, which the Bottleneck app uses to judge the hardware it measures. It is an estimate for a typical game at high settings: strategy, simulation and large multiplayer games lean on the processor more, and so do lower settings and upscaling.
An Arc B580 with the right processor can still fall short of these figures. Bottleneck checks the usual reasons a PC falls short of its parts, free: memory below its rated speed or in single channel, Resizable BAR and GPU scheduling left off, a monitor held at 60 Hz, heat. Then, while you play, it records which part set the pace in every frame.
