RX 6800 XT 16GB vs RX 6900 XT 16GB

What does this comparison mean?

RX 6900 XT 16GB delivers 28.2% more FPS than RX 6800 XT 16GB here while retaining the same 16GB memory capacity. This is an increase in measured benchmark throughput without a larger memory buffer, so an upgrade aimed specifically at fitting bigger textures or datasets needs a separate capacity check.

Both variants have 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

RX 6800 XT 16GB

The RX 6800 XT introduced RDNA 2 to this 16GB GDDR6 model in November 2020.

RX 6900 XT 16GB

The RX 6900 XT arrived in December 2020 with RDNA 2 architecture and 16GB of GDDR6. It uses the full Navi 21 configuration, rather than the reduced configuration of the RX 6800 XT.

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.
