Benchmark comparison
Estimated seconds to render one frame of each standard Blender benchmark scene. 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.
Which GPU makes more sense?
RTX 4070 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 4070 leads by 43.8% in the Renderjuice Blender benchmark model (5,399 vs 3,755). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 4070 has more scene headroom with 12 GB of VRAM versus 8 GB on RTX 3070 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 4070 is the lower-power option at 200 W TDP, compared with 290 W for RTX 3070 Ti. If render speed is close, that can make RTX 4070 easier to cool and run quietly.
Upgrade decision
RTX 4070 is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3070 Ti would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 3070 Ti vs RTX 4070
RTX 4070 leads the Blender benchmark score by 43.8%.
Fastest in Blender: RTX 4070 5,399.33 score.
Most VRAM: RTX 4070 12 GB.
Lowest power draw: RTX 4070 200 W TDP.
RTX 3070 Ti has 8 GB of VRAM, while RTX 4070 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.
