What does this comparison mean?
Moving from RX 590 8GB to Arc B580 12GB increases the recorded result from 87 to 168 FPS and graphics memory from 8GB to 12GB. The uplift is 93.1% in this workload with 4GB more capacity; the benchmark cannot tell us how much of the difference comes from memory rather than the rest of the GPU.
RX 590 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 590 8GB
The RX 590 arrived in November 2018 as a 12nm Polaris refresh with 8GB of GDDR5. It retains a separate identity from the earlier RX 580, despite their similar names and memory capacities.
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.
