What does this comparison mean?
Moving from RTX 2080 Ti 11GB to RX 6800 XT 16GB increases the recorded result from 221 to 287 FPS and graphics memory from 11GB to 16GB. The uplift is 29.9% in this workload with 5GB more capacity; the benchmark cannot tell us how much of the difference comes from memory rather than the rest of the GPU.
RTX 2080 Ti 11GB has 11GB and RX 6800 XT 16GB has 16GB 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
RTX 2080 Ti 11GB
The RTX 2080 Ti introduced Turing RTX hardware with 11GB of GDDR6. NVIDIA announced September 2018 availability.
RX 6800 XT 16GB
The RX 6800 XT introduced RDNA 2 to this 16GB GDDR6 model in November 2020.

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.
