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 8.8% in the Renderjuice Blender benchmark model (3,619 vs 3,325). 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 32 GB on AI PRO R9700 32 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
PRO W7900 48 GB is the lower-power option at 295 W TDP, compared with 300 W for AI PRO R9700 32 GB. If render speed is close, that can make PRO W7900 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
AI PRO R9700 32 GB is newer, but PRO W7900 48 GB still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
PRO W7900 48 GB leads the Blender benchmark score by 8.8%.
Fastest in Cycles: PRO W7900 48 GB 9% faster than AI PRO R9700 32 GB.
Most VRAM: PRO W7900 48 GB 50% more VRAM than AI PRO R9700 32 GB.
Lowest power draw: PRO W7900 48 GB 2% lower rating than AI PRO R9700 32 GB.
