The AMD RX 9060 is the objective winner of this comparison, securing victories in ten out of thirteen measured specifications. Its most significant technical advantage is its FP16 performance, which is 313% higher than that of the NVIDIA GTX 1660 Ti. This substantial lead in computational capability establishes the AMD RX 9060 as the superior hardware choice based on the provided data, as it outperforms the NVIDIA GTX 1660 Ti across the vast majority of the evaluated metrics.

Users prioritizing raw computational throughput should select the AMD RX 9060 to leverage its massive advantage in FP16 performance. Conversely, the NVIDIA GTX 1660 Ti remains the appropriate choice for those who specifically require a wider memory bus, as it maintains a 50% advantage in that category. Buyers should weigh the importance of these two distinct technical strengths when deciding which of these components best aligns with their specific hardware requirements.
