About these estimates

Times estimate one frame of each benchmark scene from the same runs, Blender version and backend as the displayed Cycles score. The calculation uses 240 samples for Junkshop, 256 for Monster and 300 for Classroom, plus a 19% estimation buffer. Actual project render times vary. Results from different Blender versions may not be directly comparable.

Is GTX 660 good for Blender?

A concise editorial read on where this GPU looks strong, the tradeoffs to keep in mind, and who it suits best.

What stands out

  • Kepler architecture
  • 28 nm process size

Tradeoffs to know

  • Meets Blender’s 2 GB VRAM minimum but falls below its 8 GB recommendation for Windows/Linux. Usability depends on GPU and driver compatibility and your scene’s memory needs.
  • Very low recorded benchmark throughput; not recommended as a GPU purchase for Blender rendering. This is editorial guidance, not an official minimum score. Check Blender-version support separately.
  • Limited VRAM at 2 GB
  • Not ideal for modern Blender projects

Who should choose it

  • GTX 660 is not recommended as a GPU purchase for current Blender rendering.
  • Check current GPU-rendering support. Historical benchmark results are not proof of compatibility with current Blender.
