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 679.9% in the Renderjuice Blender benchmark model (7,848 vs 1,006). 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 6800S 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 6800S 8 GB is the lower-power option at 100 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make RX 6800S 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
L40S 48 GB is the straightforward performance pick, while RX 6800S 8 GB needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
L40S 48 GB leads the Blender benchmark score by 679.9%.
Fastest in Cycles: L40S 48 GB 680% faster than RX 6800S 8 GB.
Most VRAM: L40S 48 GB 500% more VRAM than RX 6800S 8 GB.
Lowest power draw: RX 6800S 8 GB 67% 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 6800S 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.
