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 SUPER is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 4070 SUPER leads by 82.1% in the Renderjuice Blender benchmark model (6,150 vs 3,378). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 4070 SUPER has more scene headroom with 12 GB of VRAM versus 8 GB on RTX 3070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
Both cards list a 220 W TDP, so power draw is not the deciding spec on paper. Cooling, case airflow, and actual board partner limits still matter.
Upgrade decision
RTX 4070 SUPER is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3070 would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 3070 vs RTX 4070 SUPER
RTX 4070 SUPER leads the Blender benchmark score by 82.1%.
Fastest in Blender: RTX 4070 SUPER 6,150.38 score.
Most VRAM: RTX 4070 SUPER 12 GB.
RTX 3070 has 8 GB of VRAM, while RTX 4070 SUPER 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.
