You might find the following article which compared the performance of
GPU to multi-threaded CPU for some computationally heavy analysis and
found that if done correctly there is no real difference between the
two...

Oh, and hardware is hardware regardless of the OS that runs on it
(even more so since Apple started using Intel's chips a few years
back).
