The NVIDIA GTX 1660 is the objective winner of this comparison, securing victories in nine out of twelve measured specifications. Its most significant advantage over the competition is its FP32 performance, which is 135% higher. While the NVIDIA GeForce GTX 1050 Ti holds a 37% advantage in TDP, the superior processing power of the former makes it the more capable component across the majority of the evaluated technical categories.

Users prioritizing raw computational power and performance should select the NVIDIA GTX 1660 for their system. Conversely, the NVIDIA GeForce GTX 1050 Ti is the better choice for those who specifically require a lower TDP, as it remains the more efficient option in that singular metric. Your final decision should depend on whether your primary requirement is the significant increase in processing capability or the reduced power draw provided by the lower-wattage card.
