I ran a thorough battery of tests, but I am preparing for a trip and cannot present them all now, but they will appear over the next week or so. Suffice it to say that the 18 core iMac Pro resets the game in a number of areas. See my Mac wishlist and this is the iMac Pro tested here.

Adobe claimed some major progress in using CPU cores in early 2018, and the results confirm it: the 4-core 4.2 GHz 2017 iMac 5K takes about 2.9 times longer to export and about 2.5X longer to import. Awesome!

Only rarely in the past 15 years has such a huge performance gain/gap been realized; typically a new machine might be 25% faster and that was doing well. Lightroom users importing and exporting lots of files are going to love the 18 core iMac Pro.

Import without moving 552 high resolution raw files with 1:1 previews plus export to very high quality full-res JPEG.

Results below with macOS 10.13.3 including the Apple Supplementary Update. See the results from more systems with macOS 10.12.2 the review page.
