Benchmark comparison
Estimated render times for standard Blender benchmark scenes. Lower is faster.
These timings are derived from Blender Open Data benchmark medians and should be treated as comparative estimates, not guaranteed real-project render times.
Quick take on RTX 3070 vs RTX 4070 Ti
RTX 4070 Ti leads the Blender benchmark score by 96.9%.
Fastest in Blender: RTX 4070 Ti 6,657.45 score.
Most VRAM: RTX 4070 Ti 12 gb.
Lowest power draw: RTX 3070 220 w tdp.
RTX 3070 has 8 GB of VRAM, while RTX 4070 Ti has 12 GB, which matters when scenes, textures, or geometry get heavier.
If you are deciding between these cards for Blender, focus first on Blender benchmark score, VRAM capacity, memory bandwidth, and whether your scenes are likely to benefit more from raw speed or extra memory headroom. The comparison table above keeps those tradeoffs in one place.
