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 3090 is faster for Blender rendering, but RTX A6000 has more VRAM. That makes this a speed-versus-scene-headroom decision.
Blender render speed
RTX 3090 leads by 9.8% in the Renderjuice Blender benchmark model (5,825 vs 5,307). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX A6000 has more scene headroom with 48 GB of VRAM versus 24 GB on RTX 3090. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX A6000 is the lower-power option at 300 W TDP, compared with 350 W for RTX 3090. If render speed is close, that can make RTX A6000 easier to cool and run quietly.
Upgrade decision
RTX 3090 is the straightforward performance pick, while RTX A6000 needs a price, power, availability, or compatibility advantage to make more sense.
Quick take on RTX 3090 vs RTX A6000
RTX 3090 leads the Blender benchmark score by 9.8%.
Fastest in Blender: RTX 3090 5,825.23 score.
Most VRAM: RTX A6000 48 GB.
Lowest power draw: RTX A6000 300 W TDP.
RTX 3090 has 24 GB of VRAM, while RTX A6000 has 48 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.
