Which GPU should you choose for Blender?
RTX 4090 is faster for Blender rendering, but RTX PRO 5000 Blackwell 48 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 4090 leads by 5.9% in the Renderjuice Blender benchmark model (11,571 vs 10,929). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX PRO 5000 Blackwell 48 GB has more scene headroom with 48 GB of VRAM versus 24 GB on RTX 4090. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX PRO 5000 Blackwell 48 GB is the lower-power option at 300 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX PRO 5000 Blackwell 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX PRO 5000 Blackwell 48 GB is newer, but RTX 4090 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 4090 leads the Blender benchmark score by 5.9%.
Fastest in Cycles: RTX 4090 6% faster than RTX PRO 5000 Blackwell 48 GB.
Most VRAM: RTX PRO 5000 Blackwell 48 GB 100% more VRAM than RTX 4090.
Lowest power draw: RTX PRO 5000 Blackwell 48 GB 33% lower rating than RTX 4090.
Cheapest: RTX 4090 45% cheaper than RTX PRO 5000 Blackwell 48 GB.
Best value for money: RTX 4090 92% better value than RTX PRO 5000 Blackwell 48 GB.
RTX 4090 has 24 GB of VRAM, while RTX PRO 5000 Blackwell 48 GB has 48 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.
