Which GPU should you choose for Blender?
RTX 5090 is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 5090 leads by 310.1% in the Renderjuice Blender benchmark model (16,066 vs 3,917). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 5090 has more scene headroom with 32 GB of VRAM versus 20 GB on RTX A4500. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX A4500 is the lower-power option at 200 W TDP, compared with 575 W for RTX 5090. If render speed is close, that can make RTX A4500 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5090 is both the newer and faster Blender rendering choice here. The main reason to choose RTX A4500 would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5090 leads the Blender benchmark score by 310.1%.
Fastest in Cycles: RTX 5090 310% faster than RTX A4500.
Most VRAM: RTX 5090 60% more VRAM than RTX A4500.
Lowest power draw: RTX A4500 65% lower rating than RTX 5090.
Cheapest: RTX A4500 20% cheaper than RTX 5090.
Best value for money: RTX 5090 227% better value than RTX A4500.
RTX 5090 has 32 GB of VRAM, while RTX A4500 has 20 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.
