The NVIDIA RTX 4000 Ada Generation is the objective winner of this comparison, securing victory in eight out of twelve measured specifications. Its most significant advantage over the competition is its FP32 performance, which is 431% better. While the NVIDIA GTX 1660 holds its own in four specific categories, the substantial lead in raw computational throughput makes the former the clear technical superior in this head-to-head evaluation.

Users prioritizing maximum computational power should select the NVIDIA RTX 4000 Ada Generation to leverage its massive advantage in FP32 performance. Conversely, the NVIDIA GTX 1660 is the appropriate choice for budget-conscious buyers, as it offers an 82% better MSRP. Choosing between these two components depends entirely on whether your primary requirement is the high-end processing capability of the newer card or the significant cost efficiency provided by the older model.
