Which GPU should you choose for Blender?
L4 24 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
L4 24 GB leads by 20.3% in the Renderjuice Blender benchmark model (3,447 vs 2,865). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
L4 24 GB has more scene headroom with 24 GB of VRAM versus 16 GB on RX 6900 XT 16 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
L4 24 GB is the lower-power option at 72 W TDP, compared with 300 W for RX 6900 XT 16 GB. If render speed is close, that can make L4 24 GB easier to cool and run quietly.
Is the upgrade worthwhile?
L4 24 GB is both the newer and faster Blender rendering choice here. The main reason to choose RX 6900 XT 16 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
L4 24 GB leads the Blender benchmark score by 20.3%.
Fastest in Cycles: L4 24 GB 20% faster than RX 6900 XT 16 GB.
Most VRAM: L4 24 GB 50% more VRAM than RX 6900 XT 16 GB.
Lowest power draw: L4 24 GB 76% lower rating than RX 6900 XT 16 GB.
Cheapest: RX 6900 XT 16 GB 78% cheaper than L4 24 GB.
Best value for money: RX 6900 XT 16 GB 273% better value than L4 24 GB.
L4 24 GB has 24 GB of VRAM, while RX 6900 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.
