What does this comparison mean?
The RX 6800 has a relatively modest benchmark lead over the RTX 3070 but twice its memory capacity. This is the standard RX 6800, not the XT. For an existing 3070 owner, the extra 8GB may be more relevant than the small measured speed increase, depending on the workload.
RTX 3070 8GB has 8GB and RX 6800 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 3070 8GB
The RTX 3070 is an 8GB GDDR6 Ampere model. NVIDIA set its retail availability for October 2020.
RX 6800 16GB
The RX 6800 launched in November 2020 with RDNA 2 architecture and 16GB of GDDR6. It retains the memory capacity of the RX 6800 XT but uses a different GPU configuration.

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.
