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 5090 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 5090 leads by 28.5% in the Renderjuice Blender benchmark model (15,017 vs 11,688). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 5090 has more scene headroom with 32 GB of VRAM versus 24 GB on RTX 4090. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 4090 is the lower-power option at 450 W TDP, compared with 575 W for RTX 5090. If render speed is close, that can make RTX 4090 easier to cool and run quietly.
Upgrade decision
RTX 5090 is both the newer and faster Blender rendering choice here. The main reason to choose RTX 4090 would be price, availability, existing ownership, or a specific workstation requirement.
Quick take on RTX 4090 vs RTX 5090
RTX 5090 leads the Blender benchmark score by 28.5%.
Fastest in Blender: RTX 5090 15,016.75 score.
Most VRAM: RTX 5090 32 GB.
Lowest power draw: RTX 4090 450 W TDP.
RTX 4090 has 24 GB of VRAM, while RTX 5090 has 32 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.
