The NVIDIA RTX 4060 is the objective winner of this comparison, securing victories in ten out of thirteen measured categories. Its most significant technical advantage over the NVIDIA GTX 1660 Ti is its FP32 performance, which is 178% higher. While the NVIDIA GTX 1660 Ti maintains a 50% lead in memory bus width, the overall spec-based superiority of the newer card makes it the clear leader in this head-to-head evaluation.

Users prioritizing raw computational throughput should select the NVIDIA RTX 4060 to take advantage of its substantial lead in FP32 performance. Conversely, the NVIDIA GTX 1660 Ti remains the appropriate choice for specific use cases that rely heavily on a wider memory bus. Buyers should weigh the importance of these two distinct architectural strengths when deciding which component best aligns with their specific technical requirements.
