Which GPU should you choose for Blender?
RTX 3070 is faster for Blender rendering, but RX 7800 XT 16 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 3070 leads by 8.6% in the Renderjuice Blender benchmark model (2,966 vs 2,732). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 7800 XT 16 GB has more scene headroom with 16 GB of VRAM versus 8 GB on RTX 3070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RTX 3070 is the lower-power option at 220 W TDP, compared with 263 W for RX 7800 XT 16 GB. If render speed is close, that can make RTX 3070 easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7800 XT 16 GB is newer, but RTX 3070 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Comparison summary
RTX 3070 leads the Blender benchmark score by 8.6%.
Fastest in Cycles: RTX 3070 9% faster than RX 7800 XT 16 GB.
Most VRAM: RX 7800 XT 16 GB 100% more VRAM than RTX 3070.
Lowest power draw: RTX 3070 16% lower rating than RX 7800 XT 16 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
RTX 3070 has 8 GB of VRAM, while RX 7800 XT 16 GB has 16 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.
