Which GPU should you choose for Blender?
RTX 3090 Ti is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Cycles rendering performance
RTX 3090 Ti leads by 5.3% in the Renderjuice Blender benchmark model (5,271 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
RX 7900 XTX is the lower-power option at 355 W TDP, compared with 450 W for RTX 3090 Ti. If render speed is close, that can make RX 7900 XTX easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 3090 Ti is the straightforward performance pick, while RX 7900 XTX needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RTX 3090 Ti leads the Blender benchmark score by 5.3%.
Fastest in Cycles: RTX 3090 Ti 5% faster than RX 7900 XTX.
Most VRAM: Tie Same memory capacity.
Lowest power draw: RX 7900 XTX 21% lower rating than RTX 3090 Ti.
Cheapest: RX 7900 XTX 18% cheaper than RTX 3090 Ti.
Best value for money: RX 7900 XTX 16% better value than RTX 3090 Ti.
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.
