The NVIDIA RTX 4070 SUPER is the objective winner of this comparison, securing victory in nine out of thirteen measured specifications. Its most significant advantage over the NVIDIA GTX 1660 Ti is its FP32 performance, which is 552% higher. This substantial lead in raw computational capability establishes the newer card as the superior option for demanding tasks, while the older model maintains a lead in MSRP, where it is 53% better than its successor.

Users prioritizing maximum computational power and modern performance should choose the NVIDIA RTX 4070 SUPER, as its massive advantage in FP32 performance makes it the clear choice for high-end workloads. Conversely, those who are strictly budget-conscious and prioritize a lower MSRP should opt for the NVIDIA GTX 1660 Ti. This choice depends entirely on whether the user values the significant increase in raw processing capability or the lower initial cost of the older hardware.
