The new Mac Pro is clearly intended to put the maximum horsepower literally on (or under) the desk of the working video editor, graphic designer, animator, scientist and others.
Apple is banking on increased reliance on the GPU to deliver visual performance. Out of the gate, there are two built-in GPUs. Clearly this will benefit core Apple creative software, like Final Cut Pro X, but also others, including DaVinci Resolve and many of the Adobe products.
I’m not certain I’m really in the market to be owning one of these personally, but technologically the biggest risk seems to be the GPU reliance. It will be interesting to see if it pays off.
