The AMD RX 5700 XT is the objective winner of this comparison, securing a lead in ten out of thirteen measured specifications. Its most significant advantage over the competition is its FP32 performance, which is 79% higher. This substantial lead in raw computational capability establishes it as the superior choice for users prioritizing high-end processing power and technical throughput in their graphics hardware.

Users who require maximum computational performance should select the AMD RX 5700 XT for their system. Conversely, the NVIDIA GTX 1660 Ti is the better option for those who prioritize power efficiency, as it offers a 47% advantage in TDP. Choosing between these two components depends entirely on whether your primary goal is to leverage the higher FP32 performance of the former or the lower power consumption profile of the latter.
