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 4080 is the stronger Blender rendering pick here based on benchmark score.
Blender render speed
RTX 4080 leads by 41.7% in the Renderjuice Blender benchmark model (8,733 vs 6,164). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
RTX 4080 has more scene headroom with 16 GB of VRAM versus 12 GB on RTX 5070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power and cooling
RTX 5070 is the lower-power option at 250 W TDP, compared with 320 W for RTX 4080. If render speed is close, that can make RTX 5070 easier to cool and run quietly.
Upgrade decision
RTX 5070 is newer, but RTX 4080 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 4080 vs RTX 5070
RTX 4080 leads the Blender benchmark score by 41.7%.
Fastest in Blender: RTX 4080 8,733.36 score.
Most VRAM: RTX 4080 16 GB.
Lowest power draw: RTX 5070 250 W TDP.
RTX 4080 has 16 GB of VRAM, while RTX 5070 has 12 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.
