The NVIDIA GTX 1080 and the NVIDIA GTX 1660 are tied in this objective comparison, as each card leads in six out of thirteen measured specifications. The most significant advantage for the NVIDIA GTX 1080 is its shader unit count, which is 82% higher than that of its competitor. Conversely, the NVIDIA GTX 1660 provides a substantial lead in FP16 performance, boasting a 7079% advantage over the other card.

Users prioritizing raw shader capacity for their specific workloads should select the NVIDIA GTX 1080. Those who require superior FP16 performance for their computing tasks should opt for the NVIDIA GTX 1660 instead. Because these components are evenly matched across the majority of measured specifications, the final choice depends entirely on whether your primary requirement is the higher shader count or the significantly faster FP16 performance provided by these respective models.
