Poor performance on mac with AMD Radeon Pro 560 My mac is a macbook pro 2017, with AMD Radeon Pro 560.

Seeing this question How to do GPU rendering on MacBook Pro 2016 (AMD Radeon Pro 460) I also get the Cycles render to work, but it renders at slower speeds than the CPU, an intel core i7 2.8ghz.

I have set the render settings in Preferences to OpenCL, and the Scene device settings to GPU Compute. It still takes nearly 3 secs to render all 32 steps with the startup cube just set to Rendered View.

CPU settings: 1.07 sec
GPU settings: 2.82 sec

Is this just AMD not being implemented for macOS or is the Radeon Pro 560 not so Pro after all?
Actually there is one more thing you should do before trying GPU render, that GREATLY affects the render speed: the size of the render tile. By default, render tile in Blender is fairly small which works well for CPU-based rendering. However GPU renderers work faster with large render tiles, around 512px (default is 64px I think). See this article for details, step 3:

The tile size parameter:

Since I am interested in Macbook Pro performance, can you check the tile size again and post your results?
