What does this comparison mean?
Moving from RX 7800 XT 16GB to RTX 3090 Ti 24GB increases the recorded result from 305 to 360 FPS and graphics memory from 16GB to 24GB. The uplift is 18% 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 3090 Ti 24GB has 24GB and RX 7800 XT 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 3090 Ti 24GB
The RTX 3090 Ti launched in March 2022 with Ampere architecture and 24GB of GDDR6X. The Ti variant retains the capacity of the RTX 3090 while using a different GPU and memory configuration.
RX 7800 XT 16GB
The RX 7800 XT combines RDNA 3 with 16GB of GDDR6. It became available in September 2023 alongside the 12GB RX 7700 XT.

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.
