The AMD RX 6500 XT is the objective winner of this comparison, securing victory in eight out of thirteen measured fields. Its most significant technical advantage is a boost clock that is 58% higher than that of the NVIDIA GTX 1660. This substantial lead in clock speed positions the AMD RX 6500 XT as the superior choice for users prioritizing raw frequency capabilities over the memory architecture found in the alternative.

Users who prioritize high-frequency performance should select the AMD RX 6500 XT for its superior boost clock advantage. Conversely, the NVIDIA GTX 1660 remains the appropriate choice for those who require a significantly wider memory bus, which is 200% better than the implementation found on the AMD RX 6500 XT. Choosing between these two components depends entirely on whether your specific workload benefits more from the higher clock speeds or the vastly larger memory bus width.
