What does this comparison mean?
The Arc B580 adds 4GB over the RX 480 8GB and records more than twice its FPS. An older Polaris build should be checked against Intel's platform requirements before choosing this cross-vendor upgrade.
RX 480 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 480 8GB
The RX 480 launched in June 2016 and introduced AMD's Polaris architecture. This is the 8GB GDDR5 version, rather than the separately listed 4GB configuration.
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.
