What does this comparison mean?
The RTX 4090 provides 24GB against the RX 6950 XT's 16GB and records the higher result. This compares the RDNA 2 refresh with Ada, including a change in software platform. Check whether the extra capacity is needed and whether the intended applications support the GeForce workflow; neither current prices nor operating costs are measured here.
RX 6950 XT 16GB has 16GB and RTX 4090 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.
