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, and both cards have the same VRAM capacity.
Blender render speed
RTX 4090 leads by 92.8% in the Renderjuice Blender benchmark model (11,688 vs 6,062). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
Both cards have 24 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power and cooling
Both cards list a 450 W TDP, so power draw is not the deciding spec on paper. Cooling, case airflow, and actual board partner limits still matter.
Upgrade decision
RTX 4090 is the straightforward performance pick, while RTX 3090 Ti needs a price, power, availability, or compatibility advantage to make more sense.
Quick take on RTX 3090 Ti vs RTX 4090
RTX 4090 leads the Blender benchmark score by 92.8%.
Fastest in Blender: RTX 4090 11,687.5 score.
Both GPUs ship with 24 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
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.
