The AMD RX 480 and the NVIDIA GTX 1660 SUPER represent a balanced choice, as both components secure an equal number of spec victories. The primary differentiator between these two options is their specific architectural focus. The AMD RX 480 holds a significant advantage in shader units, which are 64% more numerous than those found in its competitor. Conversely, the NVIDIA GTX 1660 SUPER provides a substantial lead in FP16 performance, outperforming the alternative by 72% in that specific metric.

Users prioritizing high shader unit counts for their specific computational needs should select the AMD RX 480. This component is better suited for tasks that rely heavily on that architectural strength. Alternatively, those who require superior FP16 performance for their workflows should opt for the NVIDIA GTX 1660 SUPER. Because the overall spec comparison results in a tie, the final decision depends entirely on whether your workload benefits more from the shader count or the FP16 capability.
