The NVIDIA RTX 4060 Ti 8 GB is the objective winner of this comparison, securing victory in ten out of thirteen measured specifications. Its most significant advantage is its FP32 performance, which is 339% better than that of the NVIDIA GTX 1660. While the latter holds a 50% advantage in memory bus width, the substantial lead in raw computational throughput makes the former the superior choice across the vast majority of technical metrics.

Users prioritizing raw processing power and modern computational capabilities should select the NVIDIA RTX 4060 Ti 8 GB for its dominant FP32 performance. Conversely, the NVIDIA GTX 1660 remains a viable option for specific use cases that rely heavily on a wider memory bus. Buyers should weigh the importance of raw compute speed against the specific memory architecture requirements of their intended applications when choosing between these two components.
