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 637.0% in the Renderjuice Blender benchmark model (7,848 vs 1,065). 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 6650 XT 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 6650 XT 8 GB is the lower-power option at 176 W TDP, compared with 300 W for L40S 48 GB. If render speed is close, that can make RX 6650 XT 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
L40S 48 GB is the straightforward performance pick, while RX 6650 XT 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 637.0%.
Fastest in Cycles: L40S 48 GB 637% faster than RX 6650 XT 8 GB.
Most VRAM: L40S 48 GB 500% more VRAM than RX 6650 XT 8 GB.
Lowest power draw: RX 6650 XT 8 GB 41% lower rating than L40S 48 GB.
