The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victory in ten out of twelve measured specifications. Its most significant advantage over the AMD RX 470 is its FP32 performance, which is 1389% higher. While the AMD RX 470 maintains a lead in two categories, the massive disparity in computational power highlights the substantial technical gap between these two graphics processing units.

Users prioritizing raw computational throughput should select the NVIDIA GeForce RTX 4090D for its superior FP32 performance. Conversely, those focused on initial acquisition costs should choose the AMD RX 470, which offers an 89% advantage in MSRP. The decision rests on whether the buyer requires the extreme processing capabilities of the former or the budget-friendly pricing structure of the latter.
