What does this comparison mean?
The 5080 is a large measured jump from the 3080 and moves from 10GB to 16GB. Its advantage here is benchmark throughput, not a promise of the same gain in every game.
RTX 3080 10GB has 10GB 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
RTX 3080 10GB
The RTX 3080 opened Ampere with a major high-end performance step and a 10GB GDDR6X design. Its launch was also defined by exceptional demand; the card's technical impact is clearer than any claim about how easy it was to buy.
RTX 5080 16GB
The RTX 5080 is a capable 4K Blackwell card, yet its native-rendering advance over the 4080 Super was modest for a new generation. It remains a high-end option, with a legacy still too young to judge firmly.

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 above compares the higher model average with the lower one; the score scales every model against the fastest GPU in the current dataset, which scores 100. A benchmark result does not predict gaming FPS, and the percentage may change with the benchmark dataset.
