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 3080 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 3080 leads by 28.2% in the Renderjuice Blender benchmark model (4,812 vs 3,755). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 3080 has more scene headroom with 10 GB of VRAM versus 8 GB on RTX 3070 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 3070 Ti is the lower-power option at 290 W TDP, compared with 320 W for RTX 3080. If render speed is close, that can make RTX 3070 Ti easier to cool and run quietly.
Upgrade decision
RTX 3070 Ti is newer, but RTX 3080 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Quick take on RTX 3070 Ti vs RTX 3080
RTX 3080 leads the Blender benchmark score by 28.2%.
Fastest in Blender: RTX 3080 4,812.41 score.
Most VRAM: RTX 3080 10 GB.
Lowest power draw: RTX 3070 Ti 290 W TDP.
RTX 3070 Ti has 8 GB of VRAM, while RTX 3080 has 10 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.
