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 235.7% in the Renderjuice Blender benchmark model (11,571 vs 3,447). 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
L4 24 GB is the lower-power option at 72 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make L4 24 GB easier to cool and run quietly.
Is the upgrade worthwhile?
L4 24 GB is newer, but RTX 4090 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 4090 leads the Blender benchmark score by 235.7%.
Fastest in Cycles: RTX 4090 236% faster than L4 24 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: L4 24 GB 84% lower rating than RTX 4090.
Cheapest: Tie Same displayed price.
Best value for money: RTX 4090 236% better value than L4 24 GB.
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.
