At a Glance: Why the 2019 iMac 5K Rocks for my Photo Work, and Why the GPU is Much Less Important than 8 Fast CPU Cores
Consult with Lloyd on configuring a high performance system including data integrity and backup and workflow practices.
The 2019 iMac 5K I bought about 8 weeks ago is the best Mac for photography and my other work that I have ever used. Simply terrific! I don’t know yet, but I suspect that for my usage, it will be competitive with the new Mac Pro and maybe even faster, at a fraction of the price.
Below, one can see at a glance that a GPU is a waste of money for much of my work—it hardly gets used except when doing Enhance Details and that usage is intermittent. What do get used are the eight CPU cores (16 virtual cores). This graph over 10 minutes or so of my work in Photoshop and Zerene Stacker.
