What does this comparison mean?
The RTX 5090 records a large lead over the RX 7800 XT and doubles memory capacity to 32GB. This compares an RDNA 3 Radeon with the dataset's fastest Blackwell GeForce. It is a useful upper-end reference, but the result does not establish that the flagship is the best-value replacement for an existing 7800 XT.
RX 7800 XT 16GB has 16GB and RTX 5090 32GB has 32GB 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
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.
RTX 5090 32GB
The RTX 5090 launched in January 2025 as a Blackwell desktop GPU with 32GB of GDDR7. It is the fastest card in this GPUsed benchmark dataset, which makes its compressed rating 100.

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.
