The NVIDIA RTX 5080 is the objective winner of this comparison, securing victory in ten out of fourteen measured specifications. While the AMD RX 6950 XT holds a 20% advantage in memory clock speed, the NVIDIA RTX 5080 dominates the field with a massive 138% lead in FP32 performance. This substantial gap in raw computational capability establishes the latter as the superior component across the vast majority of technical metrics evaluated.

Users prioritizing raw computational throughput should select the NVIDIA RTX 5080 to leverage its significant lead in FP32 performance. Conversely, the AMD RX 6950 XT remains a viable alternative for specific workloads that benefit primarily from its 20% higher memory clock speed. Choosing between these two GPUs depends on whether your specific requirements favor the overwhelming computational advantage of the NVIDIA card or the specialized memory clock benefit offered by the AMD hardware.
