The M1 chip plays decidedly to the strengths that the Mac Mini had already laid as a foundation. The eight-core CPU is designed not just to improve the performance of applications running on the platform but also to be more power-efficient than the Intel chips the line previously used. The 3.2-GHz Intel Core i7 in the prior Mac Mini had a thermal design power of 65 watts. Apple hasn’t disclosed the TDP for the 3.2-GHz M1, but it appears to be in the vicinity of a mere 10 watts.
And sure enough, it runs great despite sipping at juice. Apple has thrown out a lot of self-generated honorifics about the new Mac Mini and the M1. It’s roughly 3.5 times faster on most tasks, up to six times faster on graphics (an eight-core GPU is integrated into the same silicon), and up to 15 times faster on machine-learning tasks, thanks to a 16-core “neural engine,” in case you’re trying to coax your Mac into self-awareness. Turns out these claims are all more or less justified. I don’t have the 2018 Mac Mini around to use in a side-by-side test, but my review unit churned out benchmark numbers on tools like Geekbench and Cinebench that easily best many Intel- and AMD-based PCs that I’ve tested, and which (based on previously published scores) blow older Mac hardware numbers away.
A lot of this success has to do with the fact that Apple has strongly nudged its ecosystem into embracing the M1, and it came out of the gate with a huge number of applications that have been upgraded to run as “universal” apps, programs which can run natively on the M1 and take advantage of its architecture in full. Naturally, all of Apple’s own applications are fully M1-ready, but so is a significant portion of the rest of the market. The good news is that a new version of Apple’s Rosetta emulator is always on standby to fill in any gaps, so you can still run Intel-designed applications on the Mac Mini, just a lot slower than native code. But at least it runs.
Adobe’s Creative Cloud—just as it was with Microsoft’s SQ1 chip—is the big holdout here, but a beta version of Photoshop for M1 is already out (it shipped at the same time as the version for Microsoft’s ARM chip), with a final version slated for next year. An M1-native Lightroom will also be released by the end of 2020, per Adobe. Given the importance of the Mac market to Adobe, it’s hard to imagine these apps won’t be hustled out as quickly as possible, but note that there are currently no official release dates for native versions of any of Adobe’s other apps.
Rosetta can’t run everything—any kind of Intel-era system extension won’t work on the new Mac Mini—but it didn’t choke on anything I threw at it, including games, few of which have been updated for the new hardware. I never encountered a crash during my testing and invariably found the system peppy and responsive in daily use.
