Rendering by tiles is much more effective
When opencl workgroup gets whole line of image to render then variety of fractal areas is much bigger than in smaller rectangle. Fo example all pixels are on the fractal or all are on background.

GPU doesn't provide threads like CPU. All parallel jobs execute the same line of code but with different data. If one of jobs have different result of condition than another jobs, then have to wait.
So if all parallel jobs has almost the same to do, then it's faster
