Which GPU should you choose for Blender?
RTX 4090 D is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 4090 D leads by 95.0% in the Renderjuice Blender benchmark model (9,998 vs 5,127). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 4090 D has more scene headroom with 24 GB of VRAM versus 12 GB on RTX 4070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 4070 is the lower-power option at 200 W TDP, compared with 425 W for RTX 4090 D. If render speed is close, that can make RTX 4070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4090 D is the straightforward performance pick, while RTX 4070 needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RTX 4090 D leads the Blender benchmark score by 95.0%.
Fastest in Cycles: RTX 4090 D 95% faster than RTX 4070.
Most VRAM: RTX 4090 D 100% more VRAM than RTX 4070.
Lowest power draw: RTX 4070 53% lower rating than RTX 4090 D.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
RTX 4070 has 12 GB of VRAM, while RTX 4090 D 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.
