iMac Pro May Feature Intel's Server-Grade 'Purley' Processors, ARM Coprocessor

Apple earlier this month unveiled the iMac Pro (https://www.macrumors.com/roundup/imac-pro/), a workstation-class desktop computer with up to an 18-core Intel Xeon processor, top-of-the-line Radeon Pro Vega graphics, up to 4TB of SSD storage, and up to 128GB of ECC RAM.

Apple didn't specify exactly which processors will be included in the iMac Pro, but if the blog Pike's Universum (https://pikeralpha.wordpress.com/2017/06/22/imac-pro-comes-with-security-enclave-processor/) is to be believed, it could be powered by Intel's next-generation server-grade Skylake-EX and Skylake-EP processors, which are based on a platform codenamed "Purley."





The blog, which appears to be sourcing its information from firmware files in the macOS High Sierra developer beta (https://www.macrumors.com/2017/06/21/apple-seeds-second-beta-of-macos-high-sierra/), said the iMac Pro will use Intel's new server-class LGA3647 socket (https://www.servethehome.com/big-sockets-look-intel-lga-3647/), not its high-end, desktop-class LGA2066 socket.





If the information is accurate, it suggests the iMac Pro could have truly server-grade Xeon processors, rather than using Intel's recently announced Core-X series (https://hothardware.com/news/intel-core-i9-7980xe-18-core-monster-cpu-reportedly-scheduled-for-later-this-year) of Skylake and Kaby Lake chips that still use the LGA2066 socket.





The blog added that the new iMac Pro appears to be coming with a Secure Enclave, suggesting it will have an ARM coprocessor like the MacBook Pro with Touch Bar for added security. It would also open the door to Touch ID on the iMac Pro, but Apple made no mention of the feature  when introducing the computer.

Pike's Universum revealed some of the iMac Pro's tech specs (https://www.macrumors.com/2017/04/06/imac-xeon-e3-64gb-ram-amd-late-october/) in April, two months prior to it being announced, including that it would have Xeon processors, ECC RAM, faster SSD storage, AMD graphics options, and Thunderbolt 3 ports, but some of the specific details proved to be inaccurate.





Apple said the iMac Pro will be available to order in December, starting at $4,999 in the United States.
