The NVIDIA RTX 2080 SUPER is the objective winner of this comparison, securing nine wins across the evaluated fields compared to two for the NVIDIA GTX 1660 SUPER. The most significant technical advantage belongs to the RTX 2080 SUPER, which delivers 122% better FP32 performance than its counterpart. While the GTX 1660 SUPER maintains a 67% advantage in MSRP, the superior computational power of the RTX 2080 SUPER defines the performance gap between these two graphics cards.

Users prioritizing raw computational power and high-end performance should choose the NVIDIA RTX 2080 SUPER for its substantial lead in FP32 capabilities. Conversely, the NVIDIA GTX 1660 SUPER is the appropriate selection for budget-conscious buyers who prioritize a lower MSRP over the advanced processing specifications found in the higher-tier model. Selecting between these components depends entirely on whether your primary requirement is maximizing technical performance or minimizing the initial cost of the hardware.
