Benchmark comparison
Estimated seconds to render one frame of each standard Blender benchmark scene. Lower is faster.
These timings are derived from Blender Open Data benchmark medians and should be treated as comparative estimates, not guaranteed real-project render times.
Which GPU makes more sense?
RTX A4500 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX A4500 leads by 27.9% in the Renderjuice Blender benchmark model (3,998 vs 3,125). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX A4500 has more scene headroom with 20 GB of VRAM versus 16 GB on RTX A4000. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX A4000 is the lower-power option at 140 W TDP, compared with 200 W for RTX A4500. If render speed is close, that can make RTX A4000 easier to cool and run quietly.
Upgrade decision
RTX A4500 is the straightforward performance pick, while RTX A4000 needs a price, power, availability, or compatibility advantage to make more sense.
Quick take on RTX A4000 vs RTX A4500
RTX A4500 leads the Blender benchmark score by 27.9%.
Fastest in Blender: RTX A4500 3,997.67 score.
Most VRAM: RTX A4500 20 GB.
Lowest power draw: RTX A4000 140 W TDP.
RTX A4000 has 16 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.
