Which GPU should you choose for Blender?
RX 7900 XT is faster for Blender rendering, but L4 24 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RX 7900 XT leads by 18.0% in the Renderjuice Blender benchmark model (4,068 vs 3,447). 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 20 GB on RX 7900 XT. 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 315 W for RX 7900 XT. 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 newer, but RX 7900 XT still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RX 7900 XT leads the Blender benchmark score by 18.0%.
Fastest in Cycles: RX 7900 XT 18% faster than L4 24 GB.
Most VRAM: L4 24 GB 20% more VRAM than RX 7900 XT.
Lowest power draw: L4 24 GB 77% lower rating than RX 7900 XT.
Cheapest: RX 7900 XT 79% cheaper than L4 24 GB.
Best value for money: RX 7900 XT 455% better value than L4 24 GB.
L4 24 GB has 24 GB of VRAM, while RX 7900 XT has 20 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.
