The NVIDIA GeForce RTX 5090D is the objective winner of this comparison, securing victory in ten out of twelve measured categories. Its most significant technical advantage is its FP32 performance, which is 1082% better than that of the NVIDIA GTX 1080. This massive disparity in raw computational power establishes the former as the superior component across the vast majority of the evaluated specifications.

Users requiring the highest level of FP32 performance should choose the NVIDIA GeForce RTX 5090D for their systems. Conversely, those prioritizing the initial cost of their hardware should opt for the NVIDIA GTX 1080, which holds a 74% advantage in MSRP. Selecting between these two components depends entirely on whether your primary objective is maximizing raw computational throughput or minimizing the upfront financial investment required for your build.
