I just checked some benchmarks and this one says it all. The Current high end Macbook Pro uses an AMD 560 Pro GPU and compared against the nVidia offerings its nowhere. Now yes these GPUs are desktop ones but remember since the 900 series GPUs nVidia mobile variants are within 10-20% of their desktop counterparts. Some of the nVidia mobile versions offer equal performance to the non overclocked desktop chips. https://www.videocardbenchmark.net/gpu.php?gpu=Radeon+Pro+560&id=3820 AMD are so far behind nVidia you need binoculars to see them. Are Apple going to stay the course with AMD just because they get them cheap?
