Which GPU should you choose for Blender?
RTX 5090 is faster for Blender rendering, but PRO W7900 48 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 5090 leads by 344.0% in the Renderjuice Blender benchmark model (16,066 vs 3,619). 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 RTX 5090. 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 575 W for RTX 5090. If render speed is close, that can make PRO W7900 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5090 is both the newer and faster Blender rendering choice here. The main reason to choose PRO W7900 48 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5090 leads the Blender benchmark score by 344.0%.
Fastest in Cycles: RTX 5090 344% faster than PRO W7900 48 GB.
Most VRAM: PRO W7900 48 GB 50% more VRAM than RTX 5090.
Lowest power draw: PRO W7900 48 GB 49% lower rating than RTX 5090.
