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.
