Which GPU should you choose for Blender?
RTX 4090 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX 4090 leads by 119.5% in the Renderjuice Blender benchmark model (11,571 vs 5,271). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 24 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power ratings and cooling
Both cards list a 450 W TDP, so power draw is not the deciding spec on paper. Cooling, case airflow, and actual board partner limits still matter.
Is the upgrade worthwhile?
RTX 4090 is the straightforward performance pick, while RTX 3090 Ti needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RTX 4090 leads the Blender benchmark score by 119.5%.
Fastest in Cycles: RTX 4090 119% faster than RTX 3090 Ti.
Most VRAM: Tie Same memory capacity.
Lowest power draw: Tie Same power rating.
Cheapest: RTX 3090 Ti 38% cheaper than RTX 4090.
Best value for money: RTX 4090 35% better value than RTX 3090 Ti.
Both GPUs ship with 24 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.
