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 3070 Ti is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 3070 Ti leads by 1315.6% in the Renderjuice Blender benchmark model (3,755 vs 265). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 3070 Ti has more scene headroom with 8 GB of VRAM versus 4 GB on GTX 1630. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
GTX 1630 is the lower-power option at 75 W TDP, compared with 290 W for RTX 3070 Ti. If render speed is close, that can make GTX 1630 easier to cool and run quietly.
Upgrade decision
GTX 1630 is newer, but RTX 3070 Ti still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Quick take on GTX 1630 vs RTX 3070 Ti
RTX 3070 Ti leads the Blender benchmark score by 1315.6%.
Fastest in Blender: RTX 3070 Ti 3,755.1 score.
Most VRAM: RTX 3070 Ti 8 GB.
Lowest power draw: GTX 1630 75 W TDP.
GTX 1630 has 4 GB of VRAM, while RTX 3070 Ti has 8 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.
