Which GPU should you choose for Blender?
RX 7900 XTX is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RX 7900 XTX leads by 4.8% in the Renderjuice Blender benchmark model (5,004 vs 4,774). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 7900 XTX has more scene headroom with 24 GB of VRAM versus 12 GB on RTX 3080 Ti. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 3080 Ti 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 3080 Ti easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7900 XTX is both the newer and faster Blender rendering choice here. The main reason to choose RTX 3080 Ti would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RX 7900 XTX leads the Blender benchmark score by 4.8%.
Fastest in Cycles: RX 7900 XTX 5% faster than RTX 3080 Ti.
Most VRAM: RX 7900 XTX 100% more VRAM than RTX 3080 Ti.
Lowest power draw: RTX 3080 Ti 1% lower rating than RX 7900 XTX.
Cheapest: RTX 3080 Ti 49% cheaper than RX 7900 XTX.
Best value for money: RTX 3080 Ti 88% better value than RX 7900 XTX.
RTX 3080 Ti has 12 GB of VRAM, while RX 7900 XTX has 24 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.
