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 295.5% in the Renderjuice Blender benchmark model (3,619 vs 915). 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 RX 6700S 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 6700S 8 GB is the lower-power option at 80 W TDP, compared with 295 W for PRO W7900 48 GB. If render speed is close, that can make RX 6700S 8 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 6700S 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
PRO W7900 48 GB leads the Blender benchmark score by 295.5%.
Fastest in Cycles: PRO W7900 48 GB 296% faster than RX 6700S 8 GB.
Most VRAM: PRO W7900 48 GB 500% more VRAM than RX 6700S 8 GB.
Lowest power draw: RX 6700S 8 GB 73% lower rating than PRO W7900 48 GB.
