Apple earlier this month unveiled the 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 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, said the iMac Pro will use Intel's new server-class LGA3647 socket, 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 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 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.

Apple's 'Stopping Leakers - Keeping Confidential' employee seminar is working well, I see...

Yeah, after announcing the product and everything. Some big ol' leaks going on. This news completely came out of the blue; I did a complete double-take. Jaw dropped. Spat out my coffee. Cleaned the lenses on my glasses. Checked the label on the wine bottle.

It's not like this article is stipulating could-bes based on a finite amount of potential hardware to fit either one of two sockets (either LGA3647 or LGA2066), seeing as Apple already said it'll ship with an 18-core Xeon.

It's sad when you already can foresee a product being recalled or having significant defects on their first shipment.

Please contact Apple's system and hardware design engineers and let them know about these issues you foresee, that they're not aware of, and set them straight! Apple Senior VP Dan Riccio should also be in the loop on this as well.

Assuming they will be using Xeon E5 Bronze/Silver CPUs, TDP will range between 45-160W with the 160W likely being for the top-end 26-core model. So an 18-core should be cooler and the 8-core exceptionally so.

AND they still keep releasing compute devices with the word "Pro" on it with no ability to do native CUDA workloads. I think somebody needs to sit down with the guys putting together requirements for these products and review things like this and not removing the "esc" key. I saw the dev community embrace Apple as a nice UI experience with a Linux-y backend. This type of behavior will have people getting other hardware and going back to pure Linux.

Mondo processing power, sounds awesome, would be overkill for my safari usage I think.....
Whatever else they decide to include between now and mass production, it'll be a droolworthy beast.... already working on my no doubt countless, and probably futile justification chats with my doll lol
