What does this comparison mean?
Moving from RX 6750 XT 12GB to RX 7900 XTX 24GB increases the recorded result from 209 to 539 FPS and graphics memory from 12GB to 24GB. The uplift is 157.9% in this workload with 12GB more capacity; the benchmark cannot tell us how much of the difference comes from memory rather than the rest of the GPU.
RX 6750 XT 12GB has 12GB and RX 7900 XTX 24GB has 24GB 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.

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.
