The NVIDIA RTX 4080 SUPER is the objective winner of this comparison, securing victory in ten out of thirteen measured categories. Its most significant advantage over the NVIDIA GTX 1660 is its FP32 performance, which is 938% higher. This massive disparity in raw computational capability establishes the newer card as the superior option for high-end processing tasks, while the older model remains limited by its significantly lower performance ceiling across the majority of the evaluated technical specifications.

Users prioritizing raw computational power should choose the NVIDIA RTX 4080 SUPER to leverage its substantial lead in FP32 performance. Conversely, the NVIDIA GTX 1660 is the appropriate choice for those focused on the initial cost of the hardware, as it maintains a 78% advantage in MSRP. Selecting between these two components depends entirely on whether the user requires the maximum performance potential of the newer architecture or the lower entry cost offered by the older model.
