The NVIDIA RTX 4070 SUPER is the objective winner of this comparison, securing victory in eleven out of fifteen measured specifications. While the NVIDIA RTX 3070 maintains a notable lead in memory bus width, which is 33% better than its successor, the newer card dominates in modern feature support. The most impactful advantage for the NVIDIA RTX 4070 SUPER is its inclusion of AV1 encoding, which represents a 100% improvement over the capabilities of the NVIDIA RTX 3070.

Users who prioritize advanced media production and streaming workflows should choose the NVIDIA RTX 4070 SUPER to leverage its superior AV1 encoding performance. Conversely, the NVIDIA RTX 3070 remains a viable option for those who specifically require the wider memory bus architecture for their particular computing tasks. By evaluating these distinct technical advantages, buyers can select the hardware that aligns most effectively with their specific functional requirements rather than relying on general performance metrics.
