What does this comparison mean?
The 3090 offers far more memory than the 3080 10GB but only a modest advantage in this benchmark. Its 24GB role is not captured by an FPS-only ranking.
RTX 3080 10GB has 10GB and RTX 3090 24GB has 24GB 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 3090 24GB
The RTX 3090 placed 24GB of memory and very high gaming performance in a consumer-facing Ampere card. Its defining role lies as much in creator and memory-heavy work as in gaming, where the price and positioning were harder to justify.

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.
