M1 is optimized for Mac systems in which small size and power efficiency are critically important. As a system on a chip (SoC), M1 combines numerous powerful technologies into a single chip, and features a unified memory architecture for dramatically improved performance and efficiency. M1 is the first personal computer chip built using cutting-edge 5-nanometer process technology and is packed with an astounding 16 billion transistors, the most Apple has ever put into a chip. It features the world&rsquo;s fastest CPU core in low-power silicon, the world&rsquo;s best CPU performance per watt, the world&rsquo;s fastest integrated graphics in a personal computer, and breakthrough machine learning performance with the Apple Neural Engine. As a result, M1 delivers up to 3.5x faster CPU performance, up to 6x faster GPU performance, and up to 15x faster machine learning, all while enabling battery life up to 2x longer than previous-generation Macs. With its profound increase in performance and efficiency, M1 delivers the biggest leap ever for the Mac.<\/p>\n<\/blockquote>\n\n<p><a href=\"https:\/\/www.apple.com\/newsroom\/2020\/11\/introducing-the-next-generation-of-mac\/\">Apple<\/a> (MacRumors: <a href=\"https:\/\/www.macrumors.com\/2020\/11\/10\/apple-silicon-mac-unveiled\/\">Air<\/a>, <a href=\"https:\/\/www.macrumors.com\/2020\/11\/10\/apple-unveils-13-inch-macbook-pro-apple-silicon\/\">Mini<\/a>, <a href=\"https:\/\/www.macrumors.com\/2020\/11\/10\/new-13-inch-macbook-pro-apple-silicon-unveild\/\">Pro<\/a>, <a href=\"https:\/\/news.ycombinator.com\/item?id=25049528\">Hacker News<\/a>, <a href=\"https:\/\/apple.slashdot.org\/story\/20\/11\/10\/2017200\/apple-unveils-new-m1-apple-silicon-powered-macbook-air-mac-mini-and-macbook-pro\">Slashdot<\/a>):<\/p>\n<blockquote cite=\"https:\/\/www.apple.com\/newsroom\/2020\/11\/introducing-the-next-generation-of-mac\/\">\n<p>Apple today introduced a new MacBook Air, 13-inch MacBook Pro, and Mac mini powered by the revolutionary M1, the first in a family of chips designed by Apple specifically for the Mac.<\/p>\n<\/blockquote>\n\n<ul>\n<li>This is the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Apple_motion_coprocessors\">second line<\/a> of Apple M chips.<\/li>\n<li><a href=\"https:\/\/twitter.com\/gruber\/status\/1326236328019759104\">No touchscreens<\/a>, at least not yet.
