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 86.9% in the Renderjuice Blender benchmark model (3,619 vs 1,936). 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 12 GB on RX 7800M 12 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 7800M 12 GB is the lower-power option at 180 W TDP, compared with 295 W for PRO W7900 48 GB. If render speed is close, that can make RX 7800M 12 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7800M 12 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 86.9%.
Fastest in Cycles: PRO W7900 48 GB 87% faster than RX 7800M 12 GB.
Most VRAM: PRO W7900 48 GB 300% more VRAM than RX 7800M 12 GB.
Lowest power draw: RX 7800M 12 GB 39% lower rating than PRO W7900 48 GB.
