The NVIDIA GeForce RTX 5090D is the objective winner of this comparison, securing victory in ten out of twelve measured specifications. Its most significant advantage over the AMD RX 480 is its FP32 performance, which is 1698% higher. This massive disparity in raw computational capability establishes the former as the superior component across the vast majority of technical metrics evaluated in this head-to-head assessment.

Users prioritizing maximum computational power should select the NVIDIA GeForce RTX 5090D for its substantial lead in FP32 performance. Conversely, the AMD RX 480 remains the logical choice for budget-conscious buyers, as it holds a 91% advantage in MSRP. Choosing between these two components depends entirely on whether the user requires the extreme performance ceiling offered by the former or the significant cost efficiency provided by the latter.
