Compile in Xcode in significantly less time. This results in a quantum leap in performance at a fraction of the powerВ - and a significant boost to battery life.ДЇour performance cores Our high-performance core is the worldвЂs fastest CPU core when it comes to low-power silicon 3В - and M1 has four of them combining their efforts for a massive boost in performance. They also have more powerful GPUs - the old M1 has 7 or 8 GPU cores the new versions are rocking 14 to 32.8-core CPU The powerful 8-core CPU in M1 combines four performance cores and four efficiency cores that work together to tackle demanding multithreaded tasks.

The standard M1 has four performance and four efficiency cores, where the M1 Pro and Max only have two efficiency cores, having traded in the rest for more performance ones: the cut-down eight-core M1 Pro that comes with the base 14-inch laptop has six performance cores, while the 10-core full M1 Pro and M1 Max have eight performance cores. The MacBook Pro 14- and 16-inch have to feed more power-hungry (in relative terms, at least) performance cores, and they have fewer efficient cores to make use of when youвЂ™re doing light work like checking email or browsing a website or two. This year, Apple is setting even higher expectations for battery life, even though the new laptops are supposed to be significantly more powerful. Apple quotes less runtime for the 14-inch MBP than the 13-inch one, despite the roughly 20 percent bigger battery.ДЄpple pulled this same trick last year, but it almost didnвЂ™t matter - the ARM processors lasted so much longer than IntelвЂ™s that we were willing to let it slide that the MacBook Air probably wouldnвЂ™t actually reach AppleвЂ™s estimated 18 hours of battery life.

Yes, that numberвЂ™s not based on a great metric, but thatвЂ™s also not necessarily a good sign. Plus, Apple is quoting three hours less battery life for the 14-inch than the 13-inch, despite the new laptop having a bigger battery.

The 16-inch Intel-based MacBook also had a 100Wh battery, and it only provided around eight hours of usage, despite AppleвЂ™s quoted 11-hour battery life. Again, though, these metrics only tell us so much. In terms of hard numbers, the 14-inch MacBook Pro has a 70 watt-hour battery, and the 16-inch takes it all the way up to the FAA limit of 100Wh (the 13-inch M1 MacBook Pro has a 58.2 Wh battery, for comparison). Plus, some websites will drain your battery much faster than others. Even this unflattering test (for the new MacBooks, not the old ones) has limitations: last we heard, Apple runs it using its own Safari browser instead of the more popular (and, according to macOSвЂ™s Activity Monitor, more energy-hungry) Chrome.

AppleвЂ™s estimate for the new 14-inch is 11 hours, the same as the 2020 Intel MacBook Air. Apple says the test involves browsing 25 popular websites using Wi-Fi, with screen brightness set to вЂњ8 clicks from bottom.вЂќ Under these conditions, the 16-inch MacBook Pro fails to beat even the M1 MacBook Air - it only gets 14 hours of life compared to the AirвЂ™s 15 hours. That point is backed up by the fact that AppleвЂ™s more realistic wireless web test tells a very different story. In a more realistic test, the 14-inch MacBook Pro doesnвЂ™t beat the Air - those numbers didnвЂ™t make it onstage Plus, modern CPUs have so much silicon dedicated to video playback that itвЂ™s almost become effortless for them. ThatвЂ™s not generally what people use their laptops for unless theyвЂ™re marathoning the Lord of the Rings extended cuts.

For one, Apple says these figures are derived from watching a movie using the Apple TV app. But using video playback as a measure of battery life is really only useful if youвЂ™re trying to sell a particular narrative - not if you just want to let people know how long their laptops will actually last. In its keynote and press release, Apple says the 14-inch MacBook Pro will provide 17 hours of video playback and estimates that the 16-inch model can last for an unprecedented-for-Macs 21 hours. But the metric Apple used to back up that claim is a bit suspect, and its other numbers tell a very different story. But thereвЂ™s one big question that comes with the new sizes and processors: howвЂ™s the battery life? To hear Apple tell it, itвЂ™s going to be great - the company even said onstage that the 16-inch had the best battery life ever, besting last yearвЂ™s M1 Macs (which it also boasted would have the longest-lived batteries). AppleвЂ™s new MacBook Pros are here, and they may actually live up to the вЂњProвЂќ moniker.
