The AMD RX 7900 XT is the objective winner of this comparison, securing victories in eight of the fourteen evaluated categories. Its most significant technical advantage over the competition is its FP16 performance, which is 97% higher. This substantial lead in floating-point operations establishes the card as the superior choice based on the provided specifications, outperforming the NVIDIA RTX 4080 SUPER across the majority of the measured hardware metrics.

Users prioritizing raw FP16 performance should select the AMD RX 7900 XT for their build. Conversely, the NVIDIA RTX 4080 SUPER is the appropriate choice for those who specifically require a higher count of shader units, where it maintains a 90% advantage over the alternative. Choosing between these two components depends entirely on whether your specific workload benefits more from the superior floating-point capabilities of the former or the increased shader density of the latter.
