Which GPU should you choose for Blender?
RTX 3090 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX 3090 leads by 1.7% in the Renderjuice Blender benchmark model (5,092 vs 5,004). 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
RTX 3090 is the lower-power option at 350 W TDP, compared with 355 W for RX 7900 XTX. If render speed is close, that can make RTX 3090 easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7900 XTX is newer, but RTX 3090 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 3090 leads the Blender benchmark score by 1.7%.
Fastest in Cycles: RTX 3090 2% faster than RX 7900 XTX.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RTX 3090 1% lower rating than RX 7900 XTX.
Cheapest: RX 7900 XTX 2% cheaper than RTX 3090.
Best value for money: RX 7900 XTX <1% better value than RTX 3090.
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.
