The NVIDIA RTX 3080 is the objective winner of this comparison, securing victory in seven of the thirteen evaluated categories. Its most significant technical advantage is its shader unit count, which is 518% higher than that of the alternative. While the NVIDIA GTX 1660 remains competitive in specific areas, the superior hardware architecture of the RTX 3080 provides a substantial lead in core processing capabilities across the majority of the measured specifications.

Users prioritizing budget constraints should select the NVIDIA GTX 1660, as it holds a 69% advantage in MSRP compared to the other model. Conversely, those who require maximum hardware performance and high shader density should choose the NVIDIA RTX 3080. The decision rests on whether the user values the significant cost efficiency of the former or the massive increase in shader units offered by the latter.
