Which GPU should you choose for Blender?
RTX 3080 10 GB is faster for Blender rendering, but RX 7900 XT has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 3080 10 GB leads by 3.4% in the Renderjuice Blender benchmark model (4,208 vs 4,068). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 7900 XT has more scene headroom with 20 GB of VRAM versus 10 GB on RTX 3080 10 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 7900 XT is the lower-power option at 315 W TDP, compared with 320 W for RTX 3080 10 GB. If render speed is close, that can make RX 7900 XT easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7900 XT is newer, but RTX 3080 10 GB still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 3080 10 GB leads the Blender benchmark score by 3.4%.
Fastest in Cycles: RTX 3080 10 GB 3% faster than RX 7900 XT.
Most VRAM: RX 7900 XT 100% more VRAM than RTX 3080 10 GB.
Lowest power draw: RX 7900 XT 2% lower rating than RTX 3080 10 GB.
Cheapest: RTX 3080 10 GB 20% cheaper than RX 7900 XT.
Best value for money: RTX 3080 10 GB 29% better value than RX 7900 XT.
RTX 3080 10 GB has 10 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.
