What does this comparison mean?
GTX 1660 Super 6GB leads by 29.5% in this benchmark. The RX 6500 XT 8GB still uses a PCIe 4.0 x4 link despite its extra memory, so check the host system's PCIe generation when weighing it against GTX 1660 Super 6GB; the 8GB label alone does not settle this comparison.
GTX 1660 Super 6GB has 6GB and RX 6500 XT 8GB has 8GB 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 6500 XT 8GB
Sapphire documents this RX 6500 XT with 8GB of GDDR6, RDNA 2 and a PCIe 4.0 x4 connection. It has more memory than the original 4GB version, but retains the narrow PCIe interface; its July 2022 release record refers to the later 8GB board.

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.
