Which GPU should you choose for Blender?
RTX 4080 is faster for Blender rendering, but L40S 48 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 4080 leads by 5.5% in the Renderjuice Blender benchmark model (8,284 vs 7,848). 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 16 GB on RTX 4080. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
L40S 48 GB is the lower-power option at 300 W TDP, compared with 320 W for RTX 4080. If render speed is close, that can make L40S 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4080 is the straightforward performance pick, while L40S 48 GB needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RTX 4080 leads the Blender benchmark score by 5.5%.
Fastest in Cycles: RTX 4080 6% faster than L40S 48 GB.
Most VRAM: L40S 48 GB 200% more VRAM than RTX 4080.
Lowest power draw: L40S 48 GB 6% lower rating than RTX 4080.
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 RTX 4080 has 16 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.
