iMac Pro comes with Xeon W Processor…

The wait is over. Intel today formally released the Xeon W processors and here are the three processors that will be used in the iMac Pro:

Intel® Xeon® Processor W-2135
Intel® Xeon® Processor W-2155
Intel® Xeon® Processor W-2195

The processors requires a C422 chipset for full support. Just like I said back in June. I also like what Intel did – they basically renamed the E5-1600 series. Now people know what a workstation processor is, but the Intel product specifications however still mentions: “Vertical Segment Server” and that is confusing.

Edit: There are no power management resource plists for the Xeon W processors, not even in DP-8. That also means, probably, that the board-id that I used back in June, is wrong. I think that we will find a new one some day soon.

Note: The references to Purley in the firmware were a bit puzzling, but they seem to share the same Intel source code.

Yah! Gigabyte said to provide me with a motherboard for this processor line, and Intel will ship two processors next Monday!

    • The one that Apple used for their WWDC showcase iMac Pro was 0x050652 (B-0 stepping) and 0x050654 (for the H-0 stepping). Newer processors are 0x050656 and 0x050658 but that information is still pretty much confidential. And so are the benchmark results.
