The NVIDIA RTX 5090 is the objective winner of this comparison, securing victory in ten out of thirteen measured specifications. Its most significant advantage over the AMD RX 590 is its FP32 performance, which is 1372% higher. This massive lead in raw computational capability establishes the NVIDIA RTX 5090 as the superior component for high-performance tasks, while the AMD RX 590 maintains a lead in only three categories, primarily centered on its lower MSRP.

Users prioritizing maximum computational power should choose the NVIDIA RTX 5090, as it offers a substantial advantage in FP32 performance. Conversely, the AMD RX 590 is the appropriate choice for budget-conscious buyers, as it provides an 86% better MSRP. Selecting between these two components depends entirely on whether the user requires the extreme performance capabilities of the NVIDIA RTX 5090 or the cost-effective pricing offered by the AMD RX 590.
