Which GPU should you choose for Blender?

L40S 48 GB is the stronger Blender rendering pick here based on benchmark score.

Cycles rendering performance

L40S 48 GB leads by 570.3% in the Renderjuice Blender benchmark model (7,848 vs 1,171). For render-time-first decisions, that is the card to prioritize.

VRAM and scene capacity

L40S 48 GB has more scene headroom with 48 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

CMP 40HX 8 GB is the lower-power option at 185 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make CMP 40HX 8 GB easier to cool and run quietly.

Is the upgrade worthwhile?

L40S 48 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

L40S 48 GB leads the Blender benchmark score by 570.3%.

Fastest in Cycles: L40S 48 GB 570% faster than CMP 40HX 8 GB.

Most VRAM: L40S 48 GB 500% more VRAM than CMP 40HX 8 GB.

Lowest power draw: CMP 40HX 8 GB 38% lower rating than L40S 48 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 L40S 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.
