What does this comparison mean?
These are both Ampere cards, with the RTX 3080 10GB above the RTX 3070 8GB in this test. Be careful to choose the original 10GB 3080 when comparing listings; the 12GB card is a separate variant.
RTX 3070 8GB 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
RTX 3070 8GB
The RTX 3070 is an 8GB GDDR6 Ampere model. NVIDIA set its retail availability for October 2020.
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.

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.
