The NVIDIA RTX 5060 is the objective winner of this comparison, securing victories in nine out of thirteen measured specifications. Its most significant advantage over the NVIDIA GTX 1660 SUPER is its FP32 performance, which is 281% better. While the older card maintains a 50% advantage in memory bus width, the substantial lead in raw compute power makes the newer model the superior choice across the majority of technical categories evaluated.

Users prioritizing raw computational throughput should choose the NVIDIA RTX 5060 for its massive lead in FP32 performance. Conversely, the NVIDIA GTX 1660 SUPER remains a viable option for specific use cases that rely heavily on a wider memory bus. Buyers should weigh the importance of modern compute capabilities against the specific memory architecture requirements of their intended applications to determine which of these two components best suits their hardware needs.
