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 exceeds that of the AMD RX 5600 XT by 1358%. While the latter component holds a lead in two categories, the massive disparity in raw computational power establishes the former as the superior option for high-performance tasks based on the provided specifications.

Users prioritizing maximum computational throughput should select the NVIDIA GeForce RTX 5090D to leverage its substantial lead in FP32 performance. Conversely, the AMD RX 5600 XT is the appropriate choice for buyers who prioritize a lower MSRP, as it maintains an 88% advantage in that specific category. Your final decision should depend on whether your primary requirement is the highest possible processing capability or the most favorable initial purchase cost.
