The 2017 iMac Pro here is pitted against other Macs on various Photoshop filters.
These tests are not sensitive to the amount of memory at 32GB and above, and are thus pure CPU/GPU tests since all machines used 64GB memory.
A mixed bag; the iMac Pro 18 core CPU does not make much of a case for itself.
Results below with macOS 10.13.3 including the Apple Supplementary Update. See the results from more systems with macOS 10.12.2 further below.
Below, the older Mac Pro models are clearly 'dogs' with respect to the 2017 iMac 5K and iMac Pro. The 12-core 3.46 GHz 2010 Mac Pro with the Sapphire video card (fast) is a particular laggard.
In a stunning repudiation of the purpoted prowess of the iMac Pro in basic filter operations, the iMac 5K trounces all the iMac Pro models for LenCorrections, and is little different for Blur, Various, Distort, and Sharpen.
The iMac Pro models show little variation in performance showing that at least for these filters the Vega 64 GPU has marginal value over the the Vega 56. That is indisputable, as shown by comparing the two 10-core models, which are neck and neck for most filters within 13% at best (Distort). Most of the filters benefit very little.
While the iMac Pro models beat the 2017 iMac 5K for the Noise by about 40%, this is only one filter out of seven. Not very impressive for the iMac Pro.
Perhaps Adobe will tune Photoshop to improve iMac Pro performance. But in terms of benefit right off the bat, the iMac Pro shows far inferior value here to the 2017 iMac 5K.
