The chips max out at <a href=\"https:\/\/ark.intel.com\/products\/124942\/Intel-Xeon-Gold-6146-Processor-24_75M-Cache-3_20-GHz\">4.2GHz<\/a> Turbo Boost, so at least some of the processors Apple plans to use are not yet available from Intel.<\/p>\n<p>With none of the chips lining up with Apple&#8217;s promised high-end specifications, the most likely explanation is that Intel has additional Purley chips on the horizon that have yet to be announced. Next-generation Xeon chips, codenamed Cascade Lake, won&#8217;t be available until 2018, and thus won&#8217;t be ready in time for Apple&#8217;s promised December release date.<\/p>\n<p>In late June, <em>Pike&#8217;s Universum<\/em> <a href=\"https:\/\/www.macrumors.com\/2017\/06\/22\/imac-pro-xeon-purley-arm-coprocessor\/\">dug up firmware files<\/a> from the macOS High Sierra beta suggesting the iMac Pro will use Intel&#8217;s server-class LGA3647 socket rather than the desktop-class LGA2066 socket, pointing towards the use of server-grade &#8220;Purley&#8221; Skylake-SP processors.<\/p>\n<p>Those same firmware files suggest the new iMac Pro will feature a Secure Enclave with an ARM coprocessor like the MacBook Pro with Touch Bar, but it&#8217;s unclear what that functionality will be used for. Touch ID is, however, a possibility.<\/p>\n<p>Apple&#8217;s iMac Pro is expected to be available for purchase this December, with pricing starting at $4,999 in the United States. Along with server-grade processors, the machines are expected to feature Radeon Pro Vega graphics, up to 128GB of ECC RAM, and up to 4TB of SSD storage.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Intel today unveiled its full lineup of &#8220;Purley&#8221; Xeon processors, most of which have already launched or are launching soon, but none of the chips in the lineup appear to be appropriate for Apple&#8217;s upcoming iMac Pro at the high end.
