The NVIDIA RTX 4090 is the objective winner of this comparison, securing victory in twelve out of fifteen measured specifications. Its most significant advantage over the NVIDIA RTX 3060 Ti is its FP32 performance, which is 410% better. While the NVIDIA RTX 3060 Ti maintains a lead in three specific categories, the sheer scale of the performance gap in computational throughput establishes the NVIDIA RTX 4090 as the superior component based on the provided technical data.

Users prioritizing maximum computational power should select the NVIDIA RTX 4090 to leverage its substantial lead in FP32 performance. Conversely, the NVIDIA RTX 3060 Ti is the appropriate choice for buyers who prioritize the MSRP advantage, which is 75% better than that of its counterpart. Choosing between these two components depends on whether your primary requirement is the highest possible performance ceiling or the more favorable MSRP offered by the smaller card.
