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 4090 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 4090 leads by 4306.1% in the Renderjuice Blender benchmark model (11,688 vs 265). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 4090 has more scene headroom with 24 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 450 W for RTX 4090. If render speed is close, that can make GTX 1630 easier to cool and run quietly.
Upgrade decision
RTX 4090 is the straightforward performance pick, while GTX 1630 needs a price, power, availability, or compatibility advantage to make more sense.
Quick take on GTX 1630 vs RTX 4090
RTX 4090 leads the Blender benchmark score by 4306.1%.
Fastest in Blender: RTX 4090 11,687.5 score.
Most VRAM: RTX 4090 24 GB.
Lowest power draw: GTX 1630 75 W TDP.
GTX 1630 has 4 GB of VRAM, while RTX 4090 has 24 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.
