What does this comparison mean?
Only 7 FPS separates the RTX 3080 10GB and RTX 4070 12GB in this dataset. The 4070 offers 2GB more memory and moves from Ampere to Ada, but the measured change alone is modest. An owner satisfied with a 3080 should identify the application or feature benefit they need before paying to exchange it.
RTX 3080 10GB has 10GB and RTX 4070 12GB has 12GB 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 4070 12GB
The RTX 4070 launched in April 2023 with Ada Lovelace architecture and 12GB of GDDR6X. It is separate from the RTX 4070 Super.

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.
