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 5070 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Blender render speed
RTX 5070 leads by 14.2% in the Renderjuice Blender benchmark model (6,164 vs 5,399). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
Both cards have 12 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power and cooling
RTX 4070 is the lower-power option at 200 W TDP, compared with 250 W for RTX 5070. If render speed is close, that can make RTX 4070 easier to cool and run quietly.
Upgrade decision
RTX 5070 is both the newer and faster Blender rendering choice here. The main reason to choose RTX 4070 would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 4070 vs RTX 5070
RTX 5070 leads the Blender benchmark score by 14.2%.
Fastest in Blender: RTX 5070 6,164.38 score.
Lowest power draw: RTX 4070 200 W TDP.
Both GPUs ship with 12 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
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.
