Which GPU should you choose for Blender?
RTX 5080 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 5080 leads by 16.3% in the Renderjuice Blender benchmark model (9,128 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 5080. 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 360 W for RTX 5080. If render speed is close, that can make L40S 48 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 5080 is both the newer and faster Blender rendering choice here. The main reason to choose L40S 48 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 5080 leads the Blender benchmark score by 16.3%.
Fastest in Cycles: RTX 5080 16% faster than L40S 48 GB.
Most VRAM: L40S 48 GB 200% more VRAM than RTX 5080.
Lowest power draw: L40S 48 GB 17% lower rating than RTX 5080.
Cheapest: Cannot compare Price unavailable for some GPUs.
