What does this comparison mean?
The RTX 3080 10GB leads the GTX 1080 8GB with a 2GB capacity increase. Moving from Pascal to Ampere adds a different hardware feature set, but the benchmark does not establish game-specific gains or the adequacy of the existing power supply.
GTX 1080 8GB (10 Gbps) has 8GB and RTX 3080 10GB has 10GB 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
GTX 1080 8GB (10 Gbps)
This GTX 1080 is the original Pascal configuration with 8GB of 10 Gbps GDDR5X, introduced in May 2016.
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.
Release and feature sources: GTX 1080 8GB (10 Gbps) source · RTX 3080 10GB source.
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. GTX 1080 8GB (10 Gbps) uses the 104-card GeForce GTX 1080 8GB family total; GPUsed has not split it by this exact variant. Full benchmark method.
