What does this comparison mean?
Moving from an RX 6600 to an Arc B580 adds 4GB of memory alongside a higher continuous benchmark average. It also changes the graphics platform from Radeon to Intel. Before choosing that route, check support for the exact applications and host system, since these model-level FPS figures cannot establish driver compatibility or the behaviour of a particular game.
RX 6600 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

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.
