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 3090 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 3090 leads by 72.4% in the Renderjuice Blender benchmark model (5,825 vs 3,378). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 3090 has more scene headroom with 24 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
RTX 3070 is the lower-power option at 220 W TDP, compared with 350 W for RTX 3090. If render speed is close, that can make RTX 3070 easier to cool and run quietly.
Upgrade decision
RTX 3090 is the straightforward performance pick, while RTX 3070 needs a price, power, availability, or compatibility advantage to make more sense.
Quick take on RTX 3070 vs RTX 3090
RTX 3090 leads the Blender benchmark score by 72.4%.
Fastest in Blender: RTX 3090 5,825.23 score.
Most VRAM: RTX 3090 24 GB.
Lowest power draw: RTX 3070 220 W TDP.
RTX 3070 has 8 GB of VRAM, while RTX 3090 has 24 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.
