What does this comparison mean?
Moving from RTX 3070 8GB to RTX 4080 16GB increases the recorded result from 212 to 452 FPS and graphics memory from 8GB to 16GB. The uplift is 113.2% in this workload with 8GB more capacity; the benchmark cannot tell us how much of the difference comes from memory rather than the rest of the GPU.
RTX 3070 8GB has 8GB and RTX 4080 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 3070 8GB
The RTX 3070 is an 8GB GDDR6 Ampere model. NVIDIA set its retail availability for October 2020.
RTX 4080 16GB
The RTX 4080 is the original 16GB Ada Lovelace model released in November 2022, distinct from the later RTX 4080 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.
