Results

This test is as real world as it gets, one that Lloyd does frequently for generating lens rendering aperture series, such as for this lens comparison. It is a time-consuming and work-stopping task, so performance gains are very welcome. It is a workflow that might have limited significance for the workflow of others. Still, if workflow is scripted in Photoshop, it likely applies.

This javascript-driven automation script generates series of images which does not lend itself to multiple CPU cores so it should be expected to run proportional to clock speed: turbo boost of 5.0 GHz for the 2019 iMac 5K versus 4.6 GHz for the 2017 iMac 5K, a n8.7% difference in clock speed.

The 5.8% difference is hardly noticeable, so the 2019 iMac 5K has no meaningful advantage.
