Which GPU should you choose for Blender?
RTX 4090 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 4090 leads by 1077.2% in the Renderjuice Blender benchmark model (11,571 vs 983). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 4090 has more scene headroom with 24 GB of VRAM versus 16 GB on A2 16 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
A2 16 GB is the lower-power option at 60 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make A2 16 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4090 is both the newer and faster Blender rendering choice here. The main reason to choose A2 16 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 4090 leads the Blender benchmark score by 1077.2%.
Fastest in Cycles: RTX 4090 1,077% faster than A2 16 GB.
Most VRAM: RTX 4090 50% more VRAM than A2 16 GB.
Lowest power draw: A2 16 GB 87% lower rating than RTX 4090.
Cheapest: A2 16 GB 81% cheaper than RTX 4090.
Best value for money: RTX 4090 127% better value than A2 16 GB.
A2 16 GB has 16 GB of VRAM, while RTX 4090 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.
