What does this comparison mean?
The RTX 5080 is a major benchmark step beyond the GTX 1080 and doubles memory from 8GB to 16GB. Their matching 80-class names span very different generations and do not imply the same physical or power requirements.
GTX 1080 8GB (10 Gbps) has 8GB and RTX 5080 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
GTX 1080 8GB (10 Gbps)
This GTX 1080 is the original Pascal configuration with 8GB of 10 Gbps GDDR5X, introduced in May 2016.
RTX 5080 16GB
The RTX 5080 is a 16GB Blackwell desktop model. NVIDIA documented its launch in January 2025.

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.
