What does this comparison mean?
Moving from RX 580 8GB to RX 6750 XT 12GB increases the recorded result from 79 to 209 FPS and graphics memory from 8GB to 12GB. The uplift is 164.6% 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 580 8GB has 8GB and RX 6750 XT 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 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 6750 XT 12GB
The RX 6750 XT belongs to AMD's May 2022 RDNA 2 refresh and carries 12GB of GDDR6.

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.
