Which GPU should you choose for Blender?
RTX 4070 is faster for Blender rendering, but A2 16 GB has more VRAM. That makes this a speed-versus-scene-headroom decision.
Cycles rendering performance
RTX 4070 leads by 421.6% in the Renderjuice Blender benchmark model (5,127 vs 983). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
A2 16 GB has more scene headroom with 16 GB of VRAM versus 12 GB on RTX 4070. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
A2 16 GB is the lower-power option at 60 W TDP, compared with 200 W for RTX 4070. If render speed is close, that can make A2 16 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 4070 is both the newer and faster Blender rendering choice here. The main reason to choose A2 16 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RTX 4070 leads the Blender benchmark score by 421.6%.
Fastest in Cycles: RTX 4070 422% faster than A2 16 GB.
Most VRAM: A2 16 GB 33% more VRAM than RTX 4070.
Lowest power draw: A2 16 GB 70% lower rating than RTX 4070.
Cheapest: A2 16 GB 7% cheaper than RTX 4070.
Best value for money: RTX 4070 384% better value than A2 16 GB.
A2 16 GB has 16 GB of VRAM, while RTX 4070 has 12 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.
