The NVIDIA RTX 4070 is the objective winner of this comparison, securing victory in eleven out of fifteen measured specifications. While the NVIDIA RTX 3060 Ti maintains a notable lead in memory bus width, which is 33% better than its counterpart, the newer card dominates in modern feature sets. The most impactful advantage for the NVIDIA RTX 4070 is its support for AV1 encoding, which represents a 100% improvement over the capabilities of the NVIDIA RTX 3060 Ti.

Users who prioritize advanced video encoding workflows should choose the NVIDIA RTX 4070 to leverage its superior AV1 support. Conversely, the NVIDIA RTX 3060 Ti remains a viable option for those who specifically require the 33% wider memory bus provided by its architecture. By evaluating whether your primary tasks rely on modern encoding standards or the specific memory bus configuration of the older hardware, you can select the component that best aligns with your technical requirements.
