The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victories in twelve out of fourteen measured specifications. Its most significant technical advantage is its FP32 performance, which is 354% better than that of the NVIDIA RTX 3060 Ti. While the latter component maintains a lead in two specific areas, the former demonstrates a clear dominance across the vast majority of the evaluated hardware metrics.

Users prioritizing raw computational power and the highest possible FP32 performance should select the NVIDIA GeForce RTX 4090D for their systems. Conversely, the NVIDIA RTX 3060 Ti is the appropriate choice for buyers who prioritize a lower MSRP, as it holds a 75% advantage in that category. Choosing between these two components depends entirely on whether your primary requirement is the superior technical capability of the 4090D or the cost-focused benefit of the 3060 Ti.
