Which GPU should you choose for Blender?
RTX 5070 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 5070 leads by 60.3% in the Renderjuice Blender benchmark model (5,800 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 12 GB on RTX 5070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 5070 is the lower-power option at 250 W TDP, compared with 295 W for PRO W7900 48 GB. If render speed is close, that can make RTX 5070 easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5070 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 5070 leads the Blender benchmark score by 60.3%.
Fastest in Cycles: RTX 5070 60% faster than PRO W7900 48 GB.
Most VRAM: PRO W7900 48 GB 300% more VRAM than RTX 5070.
Lowest power draw: RTX 5070 15% lower rating than PRO W7900 48 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
PRO W7900 48 GB has 48 GB of VRAM, while RTX 5070 has 12 GB, which matters when scenes, textures, or geometry get heavier.
If you are deciding between these cards for Blender, focus first on Blender benchmark score, VRAM capacity, memory bandwidth, and whether your scenes are likely to benefit more from raw speed or extra memory headroom. The comparison table above keeps those tradeoffs in one place.
