The NVIDIA RTX 2060 SUPER is the objective winner of this comparison, securing victory in seven out of thirteen measured specifications. Its most significant advantage over the competition is its memory bandwidth, which is 56% higher. While the NVIDIA GTX 1660 Ti holds its own in four categories, it ultimately falls behind in the majority of technical metrics, despite offering a 31% better TDP rating that highlights its superior power efficiency.

Users prioritizing raw data throughput and overall technical performance should choose the NVIDIA RTX 2060 SUPER for its substantial memory bandwidth lead. Conversely, the NVIDIA GTX 1660 Ti is the better option for those who value power efficiency above all else, as its lower TDP provides a clear advantage in energy consumption. Select the former for maximum capability or the latter if minimizing power draw is your primary requirement.
