The NVIDIA GTX 1660 is the objective winner of this comparison, securing more individual spec victories than the NVIDIA GTX 1660 SUPER. While the latter holds a significant lead in memory bandwidth, the former provides a more balanced configuration across the majority of measured fields. The most impactful advantage for the NVIDIA GTX 1660 is its memory clock, which performs 14% better than the alternative, offering a distinct technical edge in that specific category.

Users prioritizing the highest memory clock speed should select the NVIDIA GTX 1660, as it leads in the majority of comparable specifications. Conversely, those who require superior memory bandwidth should opt for the NVIDIA GTX 1660 SUPER, which offers a 75% advantage in that specific area. Choosing between these two components depends entirely on whether your specific workload benefits more from the higher memory clock of the first card or the increased bandwidth of the second.
