What does this comparison mean?
The RX 7800 XT records roughly three times the GTX 1660 Super's result and increases memory from 6GB to 16GB. A system built around the smaller GTX card may need more than a graphics-card swap.
GTX 1660 Super 6GB has 6GB 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
GTX 1660 Super 6GB
The GTX 1660 Super launched in October 2019 with Turing architecture and 6GB of GDDR6. It remains a GTX model rather than an RTX card.
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.
