What does this comparison mean?
The RX 580 8GB and RX 5500 XT 4GB differ by only 1 FPS here, with the older RX 580 ahead. Swapping to the newer card would halve capacity without improving this recorded result.
RX 580 8GB has 8GB and RX 5500 XT 4GB has 4GB 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.
RX 5500 XT 4GB
The RX 5500 XT 4GB launched in December 2019 with first-generation RDNA and GDDR6 memory. AMD offered both 4GB and 8GB versions, so the full memory specification matters when comparing a listing.

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.
