The NVIDIA RTX 5080 is the objective winner of this comparison, securing victory in nine out of thirteen measured specifications. Its most significant technical advantage is its FP16 performance, which is 43192% better than that of the alternative. While the NVIDIA GTX 1070 Ti holds its own in three specific areas, the substantial lead in computational throughput makes the newer card the clear leader in raw technical capability across the majority of the evaluated categories.

Users prioritizing maximum computational power should choose the NVIDIA RTX 5080 to leverage its massive advantage in FP16 performance. Conversely, the NVIDIA GTX 1070 Ti remains the logical choice for budget-conscious buyers, as it offers a 55% better MSRP. Selecting between these two components depends entirely on whether your primary requirement is the superior processing capacity of the newer model or the significant cost efficiency provided by the older hardware.
