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 26.3% in the Renderjuice Blender benchmark model (3,619 vs 2,865). 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 16 GB on RX 6900 XT 16 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 RX 6900 XT 16 GB. If render speed is close, that can make PRO W7900 48 GB 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 RX 6900 XT 16 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
PRO W7900 48 GB leads the Blender benchmark score by 26.3%.
Fastest in Cycles: PRO W7900 48 GB 26% faster than RX 6900 XT 16 GB.
Most VRAM: PRO W7900 48 GB 200% more VRAM than RX 6900 XT 16 GB.
Lowest power draw: PRO W7900 48 GB 2% lower rating than RX 6900 XT 16 GB.
