What does this comparison mean?
Moving from RX 5500 XT 4GB to GTX 1660 Super 6GB increases the recorded result from 78 to 101 FPS and graphics memory from 4GB to 6GB. The uplift is 29.5% in this workload with 2GB more capacity; the benchmark cannot tell us how much of the difference comes from memory rather than the rest of the GPU.
RX 5500 XT 4GB has 4GB and GTX 1660 Super 6GB has 6GB 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 5500 XT 4GB
The RX 5500 XT 4GB launched in December 2019 with first-generation RDNA and GDDR6 memory. AMD offered both 4GB and 8GB versions, so the full memory specification matters when comparing a listing.
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.

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.
