Apple’s Mac Professional and Professional Show XDR have been out on the earth for some time now, however Apple is simply now publishing its white papers for the 2 new units, which go into far higher element concerning the high-end {hardware}.

The truth that Apple waited months to supply this info is odd, provided that there are some necessary particulars concerning the two merchandise, together with caveats for third-party compatibility and explanations for a few of the design and spec decisions Apple made right here. It’s the type of info that you just’d most likely need earlier than you spend $6,000-plus on a brand new laptop or display, so it’s good to see that Apple is offering it now.

As one would possibly anticipate from a technical overview produced in-house by Apple, the 2 paperwork learn largely like a laundry record of Apple congratulating itself for all its innovation and spectacular specs, however they do reveal some new small particulars concerning the Mac Professional and Professional Show XDR that Apple hadn’t introduced earlier than.

Must you not have the time (or the inclination) to learn dozens of pages of technical documentation, we’ve taken the freedom of highlighting essentially the most attention-grabbing new particulars on the Mac Professional and Professional Show XDR under.

Mac Professional

  • Whereas loads of third-party websites have accomplished velocity checks evaluating Apple’s previous and new Mac Professional fashions, Apple provides the laborious numbers itself: the brand new mannequin’s processor is as much as 6.5 occasions sooner than the previous 12-core Mac Professional (relying on what you’re doing and the processor you decide), whereas the GPU can attain as much as 6.eight occasions the efficiency in comparison with the twin FirePro D700 on the 2013 mannequin.
  • Technically, the 24- and 28-core processor choices can help as much as 2TB of RAM, properly past the 1.5TB at which Apple maxes out. The reason being that providing 2TB of RAM would required unbalanced DIMM configurations (the place you have got a distinct quantity of RAM on totally different sticks), which Apple is seeking to keep away from.
  • Apple’s customized MPX modules for GPUs are large for a motive: they permit passive cooling, twin GPU modules, and “different options sooner or later.” It’s not precisely a shock that Apple needs the brand new Mac Professional to be extra modular, however right here’s the affirmation that the corporate is seeking to do extra with its flagship professional gadget.
  • Apple’s I/O card (the piece that has the headphone jack, USB-A ports, and Thunderbolt three ports) has 
“a particular connector that connects it to the DisplayPort connections routed from the MPX Modules, enabling video over its Thunderbolt three ports.” Must you not want the additional I/O ports, you can too take away it solely.
  • The Mac Professional has an inner USB-A port “for inner use,” designed for license keys for professional software program. The purpose right here is two-fold: protecting these license key drives out of the way in which, and ensuring they’re much less simply stolen.
  • All Mac Professional configurations (from Apple at the least) work fully with Home windows by way of Boot Camp… aside from Apple’s Afterburner card.
  • Apple makes some extent to notice that its pricier, larger core depend Xeon processors provide “elevated multithreaded efficiency” on the expense of “decreased base clock.” The white paper particularly tells clients that “it is very important know in case your main functions can scale to larger core counts to get most efficiency from top-end Xeon processors.” In different phrases: ensure you can really use these additional cores, otherwise you’ll get caught with a slower laptop.
  • Apple helps each third-party SATA storage and a few third-party AMD GPUs, however there are some large caveats for each. SATA storage is handled like an exterior drive from a macOS perspective, which means that it gained’t have the ability to be encrypted by Apple’s T2 co-processor, not like the principle drive. And whereas different GPUs can be utilized, they’ll want AUX energy cables (bought individually) and can stop utilizing the Mac Professional Thunderbolt three ports for video: “an Apple MPX Module is required to offer video help over Mac Professional Thunderbolt three ports; with out one, Thunderbolt three ports change into knowledge solely and are unable to gentle a show.”
  • Amusingly, Apple notes that the Mac Professional can draw a lot energy that “facility energy sources ought to be rigorously thought-about to keep away from overloading a given circuit, particularly for a completely configured system with shows and equipment, or a number of Mac Professional techniques.”

Professional Show XDR

  • The Professional Show XDR has two ambient gentle sensors, one on the entrance and one on the again, that are used to regulate backlight brightness, content material black degree, and white level (if True Tone is enabled) on the show in your given lighting setup. Apple notes right here that you need to keep away from having any vibrant lights in your desk by the again of the show (like, say, a desk lamp) to keep away from complicated the sensors.
  • One other odd caveat: Apple says that the Professional Show XDR can “maintain 1000 nits of brightness throughout your complete display indefinitely in environments as much as 25° C (77° F).” Crank the brightness up previous 1,000 nits, or the temperature previous 77 levels Fahrenheit, and the brightness might go down.
