(You may want to consider buying an even higher-end iMac Pro than the base model-many of my friends agree that the 10-core model might be the best mix of price and performance.)īut if you’re not one of those people, if you don’t need all the added niceties and the extreme performance in pro apps, there’s good news. If that sounds like you, congratulations-you’re ready to take the leap across the iMac Pro gap.

What this all suggests is that the iMac Pro is exactly what Apple says it is-a high-end iMac with a whole bunch of special high-end features that’s most appropriate for people who use high-end professional apps that have been optimized for Apple’s professional Mac architecture. The iMac Pro is a strange beast, since it’s powered by Intel Xeon processors, not Core processors, and it’s also got that T2 processor that the iMac lacks.

I’m not quite sure why this is (I’ve shared my results with Apple and am hoping to get some clarification), but my suspicion is that Apple is going the extra mile to optimize its software to take advantage of the performance of the iMac Pro. In my tests of Logic Pro X and Final Cut Pro X, both professional media applications published by Apple itself, the iMac Pro scored notably better than the iMac. There’s a little bit of a plot twist, however. Even some of my iZotope plug-ins, high-end audio software designed for professionals and costing hundreds of dollars, failed to keep the eight cores of either system engaged.

If you are encoding video or audio or working in high-end graphics, you will probably have workflows that are built to take full advantage of multiple cores, but a lot of software just doesn’t care. Just in terms of a reality check, most of the work people do on their Macs is not particularly optimized for multiple processor cores.

The high-end Core i9 iMac was faster than the iMac Pro in single-core tasks. The iMac has to make do with separate, discrete controllers for audio, system, and disk, has a lower-resolution and lower-quality FaceTime camera, and offers somewhat reduced storage speeds that lack the extra security of on-the-fly hardware encryption via the T2.

The iMac Pro’s T2 processor handles audio and system management, acts as disk controller for high-speed encrypted SSD storage, drives the high-resolution FaceTime camera, and enables a secure boot system that validates that your software hasn’t been tampered with. It’s not a good sign that the 2019 iMac is among them, because it strongly suggests that the iMac is the last of an older generation of Apple tech, while the iMac Pro is part of Apple’s modern Mac architecture. The only other current Mac models being sold without an Apple-designed ARM processor at their heart haven’t been updated in ages: the non-Retina MacBook Air, the 12-inch MacBook, and the low-end 13-inch MacBook Pro that lacks a Touch Bar. Who knows, maybe the thermal paste Apple’s using on these systems is of a higher caliber? In any event, as this Max Tech video shows, the iMac tries hard to not blow those fans while still maximizing processor speed.Īnother advantage the iMac Pro has over the iMac is that it’s a true, modern Mac, equipped with the Apple-designed T2 coprocessor to handle security, storage, and more. Though I don’t have a previous-generation model to compare it to, it does seem like this generation of iMac is a bit less aggressive at blowing its fans full blast-perhaps aided by improvements in how Intel and AMD manage CPU and GPU temperatures, respectively. AppleĪpple’s iMac Pro has a cooling system that keeps it quiet even when it’s working hard.

For comparable levels of work, such as a video export from Final Cut Pro X, my iMac Pro is nearly silent and the iMac emits a constant buzz of white noise. The iMac Pro has been completely redesigned on the inside, with the space reserved for spinning hard drive configurations in standard iMacs replaced with a new fan system that’s quiet and efficient. The first one, and probably the biggest, is the improved cooling system.
