What does this comparison mean?
The Arc B580 offers 12GB against the RX 580's 8GB and records more than twice its FPS in this workload. That is a meaningful GPU-level change, but the older Polaris system's CPU, firmware and power supply remain separate checks.
RX 580 8GB has 8GB and Arc B580 12GB has 12GB 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 B580 12GB
Intel's Arc B580 uses Xe2 architecture and has 12GB of dedicated graphics memory. Availability began in December 2024.

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.
