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 A4000 is faster for Blender rendering, but Quadro RTX 6000 has more VRAM. That makes this a speed-versus-scene-headroom decision.
Blender render speed
RTX A4000 leads by 6.3% in the Renderjuice Blender benchmark model (3,125 vs 2,939). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
Quadro RTX 6000 has more scene headroom with 24 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 260 W for Quadro RTX 6000. If render speed is close, that can make RTX A4000 easier to cool and run quietly.
Upgrade decision
RTX A4000 is both the newer and faster Blender rendering choice here. The main reason to choose Quadro RTX 6000 would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on Quadro RTX 6000 vs RTX A4000
RTX A4000 leads the Blender benchmark score by 6.3%.
Fastest in Blender: RTX A4000 3,125.19 score.
Most VRAM: Quadro RTX 6000 24 GB.
Lowest power draw: RTX A4000 140 W TDP.
Quadro RTX 6000 has 24 GB of VRAM, while RTX A4000 has 16 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.
