Are Apple’s New M1-Based Macs As Good As They Say?
In November, Apple unveiled its new M1 chip and three new Macs that use it: the MacBook Air, 13-inch MacBook Pro, and Mac mini. The M1-based MacBook Air replaces the previous Intel-based MacBook Air, but with the 13-inch MacBook Pro and the Mac mini, Apple continues to sell some Intel-based models with beefier specs—most notably a higher memory ceiling. Even though Apple makes impressive performance claims for the new Macs, the community was still somewhat skeptical. Were these new Macs as fast as Apple said? Would they be limited in some other way? And the biggest question of all, should we be buying untested M1-based Macs or tried-and-true Intel-based models? Now that these new Macs are shipping and people have had a chance to try them, let’s address these and other questions so you can plan your future Mac purchases appropriately.Of course, the top-of-the-line 28-core Mac Pro and its siblings outperform the 8-core M1-based Macs in the GeekBench 5 multi-core benchmarks, but if you focus on the new M1 Macs in the multi-core rankings below, you can see that they’re just behind the fastest 27-inch iMacs and low-end Pro models. That’s doubly impressive when you remember that the Mac Pro in the screenshot below costs $6000, compared to $700 for the Mac mini. Benchmarks don’t lie, but they also don’t tell the whole story. These new Macs feel fast. Apps launch with only a bounce or two of the icon on the Dock. The MacBook Air and MacBook Pro wake from sleep and unlock with an Apple Watch so quickly that they’re ready to use by the time you’ve finished opening the screen. We can’t promise you’ll never see the spinning beachball wait cursor, but we haven’t so far. In some ways, using these new Macs feels more like using a fast iPad or iPhone, where everything happens nearly instantly. Finally, note that only apps that have been rewritten to support the M1 chip receive the full speed boost. Older apps must be “translated” by Apple’s Rosetta 2, which converts apps from Intel instructions to the Arm instructions needed by the M1. That happens at launch, after which macOS launches the translated app. The first launch might be slow, but subsequent launches are faster. Although emulation environments are generally quite slow, early tests show apps translated by Rosetta 2 as running at about 80% of native speed. The upshot of that is that even translated apps might run faster than the equivalent app running on an Intel-based Mac.
