Which GPU should you choose for Blender?
PRO W7900 48 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
PRO W7900 48 GB leads by 22.4% in the Renderjuice Blender benchmark model (3,619 vs 2,956). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
PRO W7900 48 GB has more scene headroom with 48 GB of VRAM versus 8 GB on RTX 3070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 3070 is the lower-power option at 220 W TDP, compared with 295 W for PRO W7900 48 GB. If render speed is close, that can make RTX 3070 easier to cool and run quietly.
Is the upgrade worthwhile?
PRO W7900 48 GB is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3070 would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
PRO W7900 48 GB leads the Blender benchmark score by 22.4%.
Fastest in Cycles: PRO W7900 48 GB 22% faster than RTX 3070.
Most VRAM: PRO W7900 48 GB 500% more VRAM than RTX 3070.
Lowest power draw: RTX 3070 25% lower rating than PRO W7900 48 GB.
