Which GPU should you choose for Blender?
RX 7600 XT 16 GB is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RX 7600 XT 16 GB leads by 6.1% in the Renderjuice Blender benchmark model (1,017 vs 958). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RX 7600 XT 16 GB has more scene headroom with 16 GB of VRAM versus 8 GB on RX 6600 XT 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
RX 6600 XT 8 GB is the lower-power option at 160 W TDP, compared with 190 W for RX 7600 XT 16 GB. If render speed is close, that can make RX 6600 XT 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RX 7600 XT 16 GB is both the newer and faster Blender rendering choice here. The main reason to choose RX 6600 XT 8 GB would be price, availability, existing ownership, or a specific workstation requirement.
Comparison summary
RX 7600 XT 16 GB leads the Blender benchmark score by 6.1%.
Fastest in Cycles: RX 7600 XT 16 GB 6% faster than RX 6600 XT 8 GB.
Most VRAM: RX 7600 XT 16 GB 100% more VRAM than RX 6600 XT 8 GB.
Lowest power draw: RX 6600 XT 8 GB 16% lower rating than RX 7600 XT 16 GB.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
RX 6600 XT 8 GB has 8 GB of VRAM, while RX 7600 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.
