The NVIDIA GeForce RTX 4090D is the objective winner, securing victory in ten out of twelve comparable specifications. Its most significant advantage over the NVIDIA GTX 1070 Ti is its FP32 performance, which is 798% better. While the older card maintains a lead in two categories, the massive disparity in raw computational power establishes the newer model as the superior hardware choice based on the provided technical data.

Users prioritizing maximum computational throughput should select the NVIDIA GeForce RTX 4090D to leverage its substantial FP32 performance lead. Conversely, the NVIDIA GTX 1070 Ti remains the appropriate choice for budget-conscious buyers, as it offers a 72% advantage in MSRP. Choosing between these two components depends entirely on whether your primary requirement is the highest available processing capability or a more favorable initial cost.
