The AMD RX 9060 is the objective winner of this comparison, securing victories in nine out of thirteen measured categories. Its most significant technical advantage is its FP32 performance, which is 346% higher than that of the competition. This substantial lead in raw computational capability establishes the AMD RX 9060 as the superior option for users prioritizing pure processing power and modern architectural specifications over the specific hardware configurations offered by the alternative.

Users who require maximum FP32 performance for their workloads should choose the AMD RX 9060 to leverage its significant lead in that metric. Conversely, the NVIDIA GTX 1660 SUPER remains the preferred choice for those who specifically prioritize a wider memory bus, as it maintains a 50% advantage in that category. Selecting between these two components depends entirely on whether your specific use case demands higher computational throughput or the memory bus width provided by the NVIDIA GTX 1660 SUPER.
