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 faster for Blender rendering, but RTX 3090 has more VRAM. That makes this a speed-versus-scene-headroom decision.
Blender render speed
RTX 5070 leads by 5.8% in the Renderjuice Blender benchmark model (6,164 vs 5,825). 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 12 GB on RTX 5070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 5070 is the lower-power option at 250 W TDP, compared with 350 W for RTX 3090. If render speed is close, that can make RTX 5070 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 3090 would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 3090 vs RTX 5070
RTX 5070 leads the Blender benchmark score by 5.8%.
Fastest in Blender: RTX 5070 6,164.38 score.
Most VRAM: RTX 3090 24 GB.
Lowest power draw: RTX 5070 250 W TDP.
RTX 3090 has 24 GB of VRAM, while RTX 5070 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.
