The NVIDIA GTX 1070 Ti and the NVIDIA GTX 1660 Ti are tied in this objective comparison, as each component leads in six of the thirteen measured specifications. The most impactful advantage for the NVIDIA GTX 1070 Ti is its shader unit count, which is 58% higher than that of its competitor. Conversely, the NVIDIA GTX 1660 Ti offers a significant technical lead in FP16 performance, which is 8262% better than the alternative.

Users prioritizing raw shader capacity for their specific workloads should select the NVIDIA GTX 1070 Ti. Those who require superior FP16 performance for their computing tasks should choose the NVIDIA GTX 1660 Ti instead. Because these components are evenly matched across the majority of measured specifications, the final decision depends entirely on whether the user values the higher shader count of the former or the massive FP16 performance advantage provided by the latter.
