What does this comparison mean?
The RTX 5090 is comfortably ahead of the RTX 3080 10GB and offers 32GB of memory. This is a move from an Ampere high-end card to the fastest entry in this dataset. The large benchmark lead should be considered alongside the requirements of the exact flagship board, rather than assuming it is a simple drop-in replacement.
RTX 3080 10GB has 10GB and RTX 5090 32GB has 32GB 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.
RTX 5090 32GB
The RTX 5090 launched in January 2025 as a Blackwell desktop GPU with 32GB of GDDR7. It is the fastest card in this GPUsed benchmark dataset, which makes its compressed rating 100.

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.
