The NVIDIA RTX 2080 is the objective winner of this comparison, securing victory in eight out of thirteen measured categories. Its most significant technical advantage is its shader unit count, which is 92% higher than that of the alternative. While the NVIDIA GTX 1660 Ti remains competitive in specific areas, the superior hardware density found in the RTX 2080 establishes it as the more capable component across the majority of the evaluated specifications.

Users prioritizing raw hardware capacity and shader performance should select the NVIDIA RTX 2080 for their build. Conversely, the NVIDIA GTX 1660 Ti is the better choice for those who prioritize the MSRP, as it offers a 60% advantage in that specific category. Choosing between these two components depends entirely on whether your primary requirement is the high-end technical specification of the former or the cost-focused value proposition of the latter.
