The NVIDIA GeForce RTX 5090D is the objective winner of this comparison, securing victories in eleven out of thirteen measured specifications. Its most significant technical advantage is its FP32 performance, which is 355% better than that of the AMD RX 6900 XT. While the latter component maintains a lead in two specific areas, the former demonstrates a clear dominance across the majority of the evaluated hardware metrics.

Users prioritizing raw computational power should choose the NVIDIA GeForce RTX 5090D to leverage its substantial lead in FP32 performance. Conversely, the AMD RX 6900 XT is the logical selection for buyers who prioritize the MSRP, as it offers a 57% advantage in that category. Your final decision should depend on whether your primary requirement is the superior processing capability of the newer hardware or the cost-related benefit provided by the alternative.
