We put the iMac 5K, Mac Pro Silver Tower, and Mac Pro through their paces with different memory, storage, and/or video card options to see which workstation rigs would reign supreme.
TEST #1: diglloydMedium Photoshop Action Test
Generates a 15.7GB file using a 20,000 pixel wide image.
TEST #2: diglloydHuge Photoshop Action Test A true torture test that generates a 56GB scratch file using a 40,000 pixel wide image. Machines that can handle this test are pretty darn fast!
These tests mimic working with large images, images with many layers, or many images at once, to show memory, storage, and GPU performance.
Note: We're currently testing the 2017 iMac models and will publish the results here when testing has completed
