What does this comparison mean?
The RTX 3090 and RX 7800 XT sit close together in this workload, but their memory capacities differ considerably: 24GB against 16GB. A 3090 owner handling a project that exceeds 16GB should investigate that requirement before switching. The small benchmark lead cannot describe application compatibility, memory pressure or the running cost of either exact board.
RTX 3090 24GB has 24GB and RX 7800 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 3090 24GB
The RTX 3090 launched with the Ampere generation in September 2020, carrying 24GB of GDDR6X.

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.
