2nd paragraph from the bottom of the release: > iMac Pro now comes standard with a 10-core Intel Xeon processor. Designed for pro users who require workstation-class performance, iMac Pro features Xeon processors up to 18 cores, graphics performance up to 22 teraflops, up to 256GB quad-channel ECC memory, and a brilliant 27-inch Retina 5K display. I think just a bump in the base CPU and maybe the graphics? There is a reason it's buried deep in the PR.
