The NVIDIA RTX 3090 is the objective winner of this comparison, securing victory in eight out of fifteen total specifications. Its most significant advantage over the competition is its VRAM capacity, which is 100% better than that of the NVIDIA RTX 4070 SUPER. While the latter component holds its own across seven categories, the sheer memory volume provided by the former establishes it as the superior hardware choice based on the analyzed technical data.

Users who prioritize maximum memory capacity for intensive tasks should select the NVIDIA RTX 3090 to leverage its VRAM advantage. Conversely, those who require advanced media capabilities should choose the NVIDIA RTX 4070 SUPER, as it offers a 100% improvement in AV1 Encoding performance. Your final decision should depend on whether your specific workflow demands the expanded memory buffer of the first card or the specialized encoding efficiency of the second.
