The NVIDIA RTX 3090 wins in 8 out of 15 comparable specs. Its biggest advantage is VRAM (100% better).
RTX 4070 wins in 7 specs (AV1 Encoding: 100% better).
Recommendation
Choose RTX 3090 if you want the best overall performance — especially vram.
Choose RTX 4070 if av1 encoding matters more to you.
AI Versus Verdict
The NVIDIA RTX 3090 is the objective winner of this comparison, securing victory across eight of the fifteen evaluated specifications. The most significant advantage held by the NVIDIA RTX 3090 is its VRAM capacity, which is 100% higher than that of the NVIDIA RTX 4070. While the NVIDIA RTX 4070 also demonstrates a 100% advantage in AV1 encoding capabilities, the overall spec-win count favors the former card as the more robust hardware option.
Users who prioritize maximum VRAM for memory-intensive tasks should select the NVIDIA RTX 3090. Conversely, those who require superior AV1 encoding performance for streaming or content creation workflows should choose the NVIDIA RTX 4070. By focusing on these specific technical strengths, buyers can align their hardware choice with their primary computing needs rather than relying on general performance metrics.
