Which GPU should you choose for Blender?
RTX 3090 Ti is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 3090 Ti leads by 78.3% in the Renderjuice Blender benchmark model (5,271 vs 2,956). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 3090 Ti 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 ratings and cooling
RTX 3070 is the lower-power option at 220 W TDP, compared with 450 W for RTX 3090 Ti. If render speed is close, that can make RTX 3070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 3090 Ti 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.
Comparison summary
RTX 3090 Ti leads the Blender benchmark score by 78.3%.
Fastest in Cycles: RTX 3090 Ti 78% faster than RTX 3070.
Most VRAM: RTX 3090 Ti 200% more VRAM than RTX 3070.
Lowest power draw: RTX 3070 51% lower rating than RTX 3090 Ti.
Cheapest: RTX 3070 82% cheaper than RTX 3090 Ti.
Best value for money: RTX 3070 206% better value than RTX 3090 Ti.
RTX 3070 has 8 GB of VRAM, while RTX 3090 Ti 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.
