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 5070 Ti is faster for Blender rendering, but RTX 3090 Ti has more VRAM. That makes this a speed-versus-scene-headroom decision.
Blender render speed
RTX 5070 Ti leads by 25.1% in the Renderjuice Blender benchmark model (7,582 vs 6,062). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 3090 Ti has more scene headroom with 24 GB of VRAM versus 16 GB on RTX 5070 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 5070 Ti is the lower-power option at 300 W TDP, compared with 450 W for RTX 3090 Ti. If render speed is close, that can make RTX 5070 Ti easier to cool and run quietly.
Upgrade decision
RTX 5070 Ti is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3090 Ti would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 3090 Ti vs RTX 5070 Ti
RTX 5070 Ti leads the Blender benchmark score by 25.1%.
Fastest in Blender: RTX 5070 Ti 7,582.21 score.
Most VRAM: RTX 3090 Ti 24 GB.
Lowest power draw: RTX 5070 Ti 300 W TDP.
RTX 3090 Ti has 24 GB of VRAM, while RTX 5070 Ti 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.
