The NVIDIA GTX 1660 Ti is the objective winner of this comparison, securing victories in seven out of thirteen evaluated specifications. Its most significant advantage over the competition is its FP32 performance, which is 100% better. This substantial lead in raw computational throughput establishes it as the superior choice based on the provided technical metrics, despite the alternative hardware offering a higher count of shader units.

Users prioritizing raw FP32 performance should select the NVIDIA GTX 1660 Ti for their system configuration. Conversely, those who require a higher quantity of shader units should opt for the NVIDIA RTX 5060 Mobile, which provides a 100% advantage in that specific category. Choosing between these two components depends entirely on whether your workload benefits more from the superior computational output of the former or the increased shader capacity of the latter.
