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 187.2% in the Renderjuice Blender benchmark model (7,848 vs 2,732). 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 RX 7800 XT 16 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 7800 XT 16 GB is the lower-power option at 263 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make RX 7800 XT 16 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7800 XT 16 GB is newer, but L40S 48 GB still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
L40S 48 GB leads the Blender benchmark score by 187.2%.
Fastest in Cycles: L40S 48 GB 187% faster than RX 7800 XT 16 GB.
Most VRAM: L40S 48 GB 200% more VRAM than RX 7800 XT 16 GB.
Lowest power draw: RX 7800 XT 16 GB 12% 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 7800 XT 16 GB 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.
