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 FP32 performance, which is 346% higher than that of the NVIDIA GTX 1660. This substantial lead in raw computational throughput establishes the AMD RX 9060 as the superior component across the majority of the evaluated hardware categories.

Users prioritizing raw computational power should select the AMD RX 9060 to leverage its massive advantage in FP32 performance. Conversely, the NVIDIA GTX 1660 remains the appropriate choice for those whose specific requirements prioritize a wider memory bus, where it maintains a 50% advantage over the competitor. Choosing between these two components depends entirely on whether your workload benefits more from the superior processing capabilities of the former or the memory architecture of the latter.
