Which GPU should you choose for Blender?
L4 24 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
L4 24 GB leads by 194.4% in the Renderjuice Blender benchmark model (3,447 vs 1,171). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
L4 24 GB has more scene headroom with 24 GB of VRAM versus 8 GB on CMP 40HX 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
L4 24 GB is the lower-power option at 72 W TDP, compared with 185 W for CMP 40HX 8 GB. If render speed is close, that can make L4 24 GB easier to cool and run quietly.
Is the upgrade worthwhile?
L4 24 GB is both the newer and faster Blender rendering choice here. The main reason to choose CMP 40HX 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
L4 24 GB leads the Blender benchmark score by 194.4%.
Fastest in Cycles: L4 24 GB 194% faster than CMP 40HX 8 GB.
Most VRAM: L4 24 GB 200% more VRAM than CMP 40HX 8 GB.
Lowest power draw: L4 24 GB 61% lower rating than CMP 40HX 8 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
CMP 40HX 8 GB has 8 GB of VRAM, while L4 24 GB has 24 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.
