What does this comparison mean?
GTX 980 Ti 6GB is ahead in this benchmark with 6GB, while RX 580 8GB carries 8GB. Choosing the benchmark leader gives up 2GB of capacity for 29.1% more FPS in this workload; check the memory demands of your actual games or applications before making that trade.
GTX 980 Ti 6GB has 6GB and RX 580 8GB has 8GB 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
GTX 980 Ti 6GB
The GTX 980 Ti arrived in June 2015 with Maxwell architecture and 6GB of GDDR5. It is distinct from the 4GB GTX 980 and from the later Pascal GTX 1080 Ti.
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.

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.
