The AMD RX 9060 XT 16 GB is the objective winner of this comparison, securing victories in ten out of thirteen measured categories. Its most significant technical advantage is its FP16 performance, which is 372% better than that of the NVIDIA GTX 1660 Ti. This substantial lead in floating-point processing capability establishes the AMD RX 9060 XT 16 GB as the superior component across the majority of the evaluated hardware specifications.

Users prioritizing raw processing power should select the AMD RX 9060 XT 16 GB for its dominant lead in FP16 performance. Conversely, the NVIDIA GTX 1660 Ti remains a viable alternative for specific use cases that rely on a wider memory bus, where it maintains a 50% advantage over the competitor. Choosing between these two components depends on whether your workload benefits more from the superior processing throughput of the AMD card or the memory bus width of the NVIDIA option.
