What does this comparison mean?
The RX 6800 XT and RTX 3080 10GB are close in this benchmark, with the Radeon ahead by 9 FPS. Capacity is a much larger distinction: 16GB versus 10GB. A choice between them should weigh whether that memory is useful to the intended workload, rather than interpreting a small synthetic difference as a universal gaming lead.
RTX 3080 10GB has 10GB 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 3080 10GB
This RTX 3080 is the original Ampere configuration with 10GB of GDDR6X, launched in September 2020, rather than the later 12GB model.
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.
