RX 580 8GB vs Arc A580 8GB

What does this comparison mean?

Arc A580 8GB delivers 78.5% more FPS than RX 580 8GB here while retaining the same 8GB memory capacity. This is an increase in measured benchmark throughput without a larger memory buffer, so an upgrade aimed specifically at fitting bigger textures or datasets needs a separate capacity check.

Both variants have 8GB of graphics memory. Memory capacity, board dimensions, power connectors and the price of a particular used card are separate from this benchmark. Compare the exact item before deciding whether to upgrade.

The two GPUs in context

RX 580 8GB

The RX 580 8GB is a Polaris-generation Radeon introduced in April 2017. This comparison uses the 8GB variant, rather than the separate 4GB card.

Arc A580 8GB

The Arc A580 is an 8GB Intel A-series model introduced in October 2023. Intel documents hardware AV1 encoding independently of gaming performance.

How the figures are compared

Both FPS figures come from the owner-supplied GPUsed benchmark dataset. GPUsed reports a continuous FurMark run at 1080p for its physical-card checks. The percentage compares the higher model average with the lower one using the original FPS values. Our rating uses a compressed scale, with the fastest GPU at 100; it is separate from the percentage difference. A benchmark result does not predict gaming FPS.

GPUsed reports its physical-card checks typically last 30 to 60 minutes while temperature and stability are checked. The owner supplied the model-level FPS workbook on 2 October 2026; this benchmark dataset was last reconciled 3 October 2026. Historical cards tested are separate from the number of FPS runs behind a model average. Full benchmark method.
