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 902.8% in the Renderjuice Blender benchmark model (7,848 vs 783). 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 RX 6600 XT 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 6600 XT 8 GB is the lower-power option at 160 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make RX 6600 XT 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 RX 6600 XT 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
L40S 48 GB leads the Blender benchmark score by 902.8%.
Fastest in Cycles: L40S 48 GB 903% faster than RX 6600 XT 8 GB.
Most VRAM: L40S 48 GB 500% more VRAM than RX 6600 XT 8 GB.
Lowest power draw: RX 6600 XT 8 GB 47% 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.
L40S 48 GB has 48 GB of VRAM, while RX 6600 XT 8 GB has 8 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.
