What does this comparison mean?
RTX 3080 Ti 12GB is ahead in this benchmark with 12GB, while RX 6800 XT 16GB carries 16GB. Choosing the benchmark leader gives up 4GB of capacity for 5.2% more FPS in this workload; check the memory demands of your actual games or applications before making that trade.
RX 6800 XT 16GB has 16GB and RTX 3080 Ti 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 6800 XT 16GB
The RX 6800 XT introduced RDNA 2 to this 16GB GDDR6 model in November 2020.
RTX 3080 Ti 12GB
The RTX 3080 Ti arrived in June 2021 with Ampere architecture and 12GB of GDDR6X memory. It is a separate configuration from both versions of the non-Ti RTX 3080.

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.
