Which GPU should you choose for Blender?
RX 7900 XTX is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RX 7900 XTX leads by 45.2% in the Renderjuice Blender benchmark model (5,005 vs 3,447). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
Both cards have 24 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power ratings and cooling
L4 24 GB is the lower-power option at 72 W TDP, compared with 355 W for RX 7900 XTX. 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 XTX 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 XTX leads the Blender benchmark score by 45.2%.
Fastest in Cycles: RX 7900 XTX 45% faster than L4 24 GB.
Most VRAM: Tie Same memory capacity.
Lowest power draw: L4 24 GB 80% lower rating than RX 7900 XTX.
Cheapest: RX 7900 XTX 55% cheaper than L4 24 GB.
Best value for money: RX 7900 XTX 223% better value than L4 24 GB.
Both GPUs ship with 24 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
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.
