The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victories in twelve out of fourteen measured specifications. Its most significant advantage over the NVIDIA RTX 3070 is its FP32 performance, which is 262% higher. This substantial lead in raw computational capability establishes the former as the superior hardware option across the vast majority of technical categories evaluated in this assessment.

Users prioritizing maximum computational power should select the NVIDIA GeForce RTX 4090D to leverage its massive advantage in FP32 performance. Conversely, the NVIDIA RTX 3070 remains the logical choice for buyers focused on the MSRP, where it maintains a 69% advantage. Choosing between these two components depends entirely on whether your primary requirement is the highest possible technical output or the most favorable initial cost as defined by these specific metrics.
