The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victories in eleven out of thirteen measured categories. Its most significant technical advantage is its FP32 performance, which exceeds that of the AMD RX 6800 XT by 255 percent. While the latter component remains competitive in specific areas, the former demonstrates a clear dominance across the majority of the evaluated hardware specifications.

Users prioritizing raw computational power and the highest possible FP32 performance should choose the NVIDIA GeForce RTX 4090D for their systems. Conversely, the AMD RX 6800 XT is the more suitable option for budget-conscious buyers, as it holds a 59 percent advantage in MSRP. Selecting between these two components depends entirely on whether the user values the superior technical throughput of the former or the cost efficiency offered by the latter.
