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 132.5% in the Renderjuice Blender benchmark model (11,571 vs 4,977). 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
RTX A5500 is the lower-power option at 230 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX A5500 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4090 is the straightforward performance pick, while RTX A5500 needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RTX 4090 leads the Blender benchmark score by 132.5%.
Fastest in Cycles: RTX 4090 132% faster than RTX A5500.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RTX A5500 49% lower rating than RTX 4090.
Cheapest: RTX A5500 5% cheaper than RTX 4090.
Best value for money: RTX 4090 121% better value than RTX A5500.
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.
